Special Issue Information

Dear Colleagues,

As the population grows rapidly and the economy develops continuously all over the world, energy consumption and the demand for space are rapidly increasing, and it has become an inevitable trend to seek deep resources and space. With the rapid development of deep underground engineering, the risk of dynamic disaster increases significantly, caused by high temperature, high stress, or high water pressure, posing a significant threat to the normal operation of deep underground engineering and the life safety of operators.

Dynamic disaster in deep underground engineering mainly involves the deformation and failure of rock materials. Considering the complexity of rock materials, it is necessary to carry out laboratory experiments on macroscopic mechanical responses and microscopic fracture characteristics to reveal dynamic disaster evolution mechanisms as well as identify precursor information, and then apply them in the field; however, up to now, the combination of laboratory experiments and field applications of dynamic disasters is poor, hindering the technological development of monitoring and preventing dynamic disasters in deep underground engineering. Consequently, this Special Issue aims to provide an opportunity for researchers around the globe to conduct a broader scientific and technological discussion on monitoring and preventing dynamic disasters in deep underground engineering. The discussion topics include but are not limited to, dynamic disaster mechanisms, dynamic disaster prediction, and dynamic disaster control. Original research and review articles are welcome.

The uniaxial compression experiments and acoustic emission (AE) monitoring are conducted to investigate the macroscopic mechanical behavior and microscopic fracture characteristics of limestone samples with varying moisture contents. The findings revealed that as the moisture content increases from 0 to 6.6%, there is a decrease in peak stress and an increase in peak strain. A clear trend towards greater complexity in fracture characteristics is observed with increasing moisture content. In addition, AE activities demonstrate a heightened frequency, accompanied by an elevation in the corresponding multifractal parameter Δα as the moisture content rises. These variations are attributed to the increase in moisture content, which promotes the proliferation of small-scale microcracks and inhibits their evolution into large-scale microcracks. Consequently, the damage and failure process of the limestone samples transitions from being predominantly controlled by a few large-scale microcracks to being collectively influenced by a multitude of small-scale microcracks as the moisture content increases. In conjunction with the Criterion of Microcrack Density, the correctness of the analysis above is substantiated through mathematical derivation. Further, a quantitative model that links the microcrack system to moisture content is established based on the multifractal parameter Δα. Following this, a characterization model that depicts the macroscopic mechanical properties of limestone affected by moisture content is developed. This model effectively encapsulates the quantitative relationship between moisture content and the macroscopic characteristics of limestone and is validated through fitting experimental data. This research contributes to understanding the macroscopic mechanical response and microscopic fracture characteristics of limestone samples with different moisture contents, providing valuable insights and guidance for ensuring safety during engineering construction processes.

Squeezed branch piles, which boast the advantages of great bearing capacity, small settlement, and good stability, are an important infrastructure in the foundation of buildings, and their safety state is related to the safety of the entire structure. As a non-destructive testing method, surface potential can be used to effectively evaluate the damaged state of a pile foundation without destroying its stability. On this basis, in this study, the characteristics of surface potential change during settlement and deformation of squeezed branch piles under graded loading were tested and analyzed with the aid of a self-made loading system of reaction beams and an LB-IV multi-channel potential data acquisition system. The results show that: Under graded loading, squeezed branch piles can produce surface potential signals whose intensity can well reflect the settlement and local failure characteristics of the pile foundation; The potential signals change in advance of load; and they fluctuate violently before local fracturing of squeezed branch piles. The unstable fluctuation of the potential signal can be regarded as a precursor to the fracturing of squeezed branch piles. The research results have positive theoretical significance and important application value for assessing the stability of both branch piles and their stress states on site and monitoring and forecasting the disaster of pile foundation instability.
