A decoupled ALE method of implicit stabilized node-based smoothed finite element and its applications to large deformation analysis
Large deformation of soil mass has often been encountered in geotechnical analysis. When the small deformation assumption-based finite element method is applied to such large deformation analysis, the computational errors can be accumulated or the computational process may be terminated due to mesh…

Field test study on diffusion characteristics of grout in saturated sand under radial vibration
Current vibration grouting experiments typically utilize axial vibration methods, concentrating the vibration energy primarily at the end of the drill rod, thereby causing minimal radial disturbance to the surrounding soil. To address this issue, we develop a vibration grouting test system with…

Influence of site soil plastic deformation on seismic response of precast horseshoe-shaped tunnel structure
Because of strong nonlinear features of soils, the site always plastically deforms after a seismic excitation, which will have additional loading effects for underground structures buried in soil. But the effects are not taken into account in the current seismic design methods, which may bring up…
