Special Issue Information

Dear Colleagues,

Improving the soil or rock properties that support buildings is an important issue for scientists and engineers.

The functional characteristics of soil or rock not only depend on the composition and structural form of the soil, but also on various treatment methods.

The purpose of modern foundation treatment is to improve technical equipment and process parameters, as well as the composition and structure of rock and soil, in order to achieve high bearing capacity, high water stability, low interface resistance, and many other characteristics.

This Special Issue will focus on new perspectives regarding engineering materials and technical measures to improve the chemical or functional properties of soil or rock.

The topics discussed in this Special Issue will not only focus on the further processing of modern methods, technologies, and materials, but also on the verification of their characteristics through various civil engineering practices.

This research addresses the characteristics of soft soil subgrades treated by soilbags filled with excavated clayey soil. We evaluated of the strength and deformation modulus of soilbags containing excavated soil using unconfined compression tests. In addition, the drainage consolidation characteristics of soilbag-treated subgrades were investigated via model consolidation tests. Furthermore, a practical application included the construction of a 100 m-long rural road subgrade with these soilbags. The field test and numerical simulation results included the surface settlement and pore water pressure during and after construction to validate the effectiveness of the soilbag treatment for soft soil subgrade. The results show that the soilbags significantly enhanced both the strength and deformation modulus of the soft soil, which met the design requirements after the soilbag treatment. The drainage attributes of the soilbag treatment were also found to support the consolidation process of the soft soil subgrade effectively. Notably, the pore water pressure diminished rapidly during the construction interval, which is beneficial to reducing the post-construction settlement. The settlement uniformity of the subgrade is good verification of the superiority of the soilbag-treated subgrades. Full article
