Special Issue Information

Dear Colleagues,

We are now open for submissions to ” Engineering Ground and Groundwater Engineering”, a Special Issue of Applied Sciences.

Human engineering activities have a great impact on the geological environment. Groundwater, as the main element of the geological body, plays an important mediating role in this process. Its occurrence and migration law has changed due to the interference of human activities, and its initial boundaries and other conditions have changed greatly, forming a complex seepage system. Because it is invisible and flowable, it is difficult to accurately grasp its migration law, which has produced more uncertainty for engineering construction, formed greater risks and even caused serious harm; it has become a hot issue in engineering construction and geological environment protection. In recent years, groundwater disasters have occurred frequently in engineering construction, and the corresponding groundwater engineering technology has made great progress. This Special Issue is now open to collect research summarizing the latest research progress in this field and provide a learning and exchange platform for engineering peers.

The main objective of this Special Issue is to study groundwater problems in engineering construction and engineering problems in groundwater disposal. The first topic more concerns the scientific problem of the movement law of groundwater in the geological body after the transformation of human engineering activities, as well as diseases or disasters caused by the improper disposal of groundwater. The latter refers to the artificially created engineering measures that need to be adopted when problem of groundwater has to be tackled in a project, as well as the powerful experiences and lessons derived from occurrences of improper disposal. Both engineering groundwater and groundwater engineering involve engineering practice. Therefore, this Special Issue involves not only theoretical research, but also engineering practice. Potential authors include experts from universities, research institutes, engineering construction, design, construction, operation and maintenance units.

To achieve this goal, the research topics to be collected in this Special Issue include but are not limited to:

  1. Impact of human engineering activities on groundwater and feedback mechanism of groundwater on engineering activities;
  2. Theory and calculation method of engineering groundwater flow;
  3. Multifield coupling theory in engineering groundwater analysis;
  4. Groundwater disaster mechanism for engineering;
  5. Engineering groundwater test technologies: new theories and methods;
  6. Engineering groundwater monitoring technologies and test methods;
  7. Advanced geological prediction technology and methods of engineering groundwater;
  8. Groundwater control technology (curtain, pumping and recharge);
  9. Groundwater control works (foundation pit, tunnel, dam, slope and foundation);
  10. Artificial intelligence technology and application of groundwater engineering;
  11. Case analysis of groundwater engineering and engineering groundwater.

In large-scale water diversion projects, especially in the central and western regions of China, long-distance deep buried tunnels are generally involved. Therefore, it is essential to carry out field tests to obtain the permeability of the rock mass through which tunnels pass. However, the test holes of large-scale water diversion projects are basically located in mountain areas with complex hydrogeological conditions. Meanwhile, the test holes are far apart and large in depth. As a result, traditional pumping tests cannot meet the requirements. Therefore, the slug test was chosen as the main test method, and the calculation results of the water injection test, the water pressure test and the slug test are analyzed and compared. The calculation results of the three test methods are basically consistent. However, the water injection test and the water pressure test are difficult to implement at a large scale due to many environmental constraints, complex test equipment, long test periods and other factors. Furthermore, the Kipp model, the CBP model and the proposed HWS model, considering the effect of the finite thickness well-skin layer for the first time, were used to analyze and process the slug test data, respectively. The curve fitting effect of the Kipp model was the best, but the calculations were generally larger. The difference between the CBP model and the proposed HWS model is smaller in the calculation results; however, the curve fitting effect of the CBP model is the worst, and the CBP model needs to be further improved. The curve fitting effect of the proposed HWS model was between that of the Kipp model and the CBP model, and the proposed HWS model can be applied to the parameter calculations of the slug test with well-skin. In general, with reference to the criteria for the damping coefficient of the aquifer in the Kipp model, the Kipp model was applicable to the slug test for test holes without well-skin and an aquifer damping coefficient between 0.1 and 5.0. The CBP model was applicable to the slug test under the conditions of no well-skin and an aquifer damping coefficient greater than 2.0. The novel proposed HWS model was applicable to the slug test when the aquifer damping coefficient was greater than 1.0 under the conditions of no well-skin, positive well-skin and negative well-skin.

The multi-aquifer and multi-aquitard system (MAMA) is a typical geological structure in deltas. Thus, the risks and challenges to settlement control and environmental protection are increased when demand for underground space extends to deeper strata. In this study, dewatering-induced stratified settlement in MAMA is divided into three stages according to whether the overlying aquitard is coupled with groundwater seepage. Subsequently, large physical model tests were carried out. Seepage and compression in the overlying strata come after the compression in the confined aquifer and the coordinated deformation in the overlying strata. The soil is compressed under the seepage drive within the hydraulic gradient range, while the soil above it is still affected by coordinated deformation and shows expansion. Dewatering-induced uneven settlement will cause damage to existing foundations and underground structures. Large-scale and uninterrupted excavation and dewatering are the main reasons for the continuous development of land subsidence. Although artificial groundwater recharging can reduce the settlement of the existing building, underground structure, and surrounding strata, a reasonable space arrangement is needed. Full article

Based on the proposed calculation method for determining the different dip angle fracture permeability coefficients derived from the well flow vibration equation and the self-developed slug test system, research on the slug test in a field in fractured rock mass was carried out based on the underground water sealed cavern project of the National Huangdao Petroleum Reserve. The formation lithology of the test site was granite gneiss, and the fractures were not developed, which is conducive to the research of slug tests on fracture permeability. On the basis of obtaining the geological information of boreholes by using the self-developed slug test system, comparative research on the segmented slug test and conventional water pressure test was carried out. The test results show that the proposed slug test method and self-developed test system has good accuracy and applicability for determining the fracture permeability coefficient, equivalent permeability coefficient and rock mass permeability coefficient tensor, which is more convenient and efficient than other test methods.

Building deep shafts in water-rich granite formations with large fissures has difficulties, such as high-water pressure and high construction risks, and is prone to water inrush and shaft flooding. This paper relies on the No. 1 vertical auxiliary shaft project of Gaoligongshan tunnel and obtains the uneven distribution of water pressure on the outside of the lining in the horizontal direction through on-site monitoring data. In order to explain this phenomenon, based on the statistical parameters of actual fractures in the field and the Monte Carlo method, the DFN built in FLAC3D6.0 is used to generate a discrete fracture network, and a dual medium model, considering the distribution of large fractures, is established. The reason for the uneven distribution of water pressure is obtained through research: the large fissures in the surrounding rock make the hydraulic conductivity of each part of the stone body formed after grouting of the surrounding rock different. This results in different osmotic pressures from the hydrostatic pressure outside the grouting ring to the outside of the lining through the grouting ring. Based on the distribution characteristics of water pressure outside the lining, the safety of the lining under non-uniform pressure is studied. The lining safety factor is defined as the ratio of the lining’s normal service limit state load to the actual load. The normal service limit state load is the load when the RFPA software is used to establish a load-structure model to simulate the load when the lining has obvious cracks under the action of external load; the actual load is the monitoring load. The new method and mine design code method are used to evaluate the lining safety and make a comparative analysis. The results show that the new method can effectively calculate the lining safety factor and has a larger safety reserve. Full article
