..., it is not possible to determine the strike, dip and characteristics of the weak rock layers that are often encountered in construction practice in our country. This, possibly the main reason, makes the analysis of slope slope stability analysis under design inefficient and unreliable. As a result, during the cutting...

To study the deformation and failure mechanisms of the coal wall...

... Abstract Many tunnels face large soft rock deformation problems in Southeast China. Double-layer's initial support could effectively solve the problem of large deformation in soft rock tunnels, which can flexibly control the timing and ensure support stability. Combined with the Yuntunbao...

... Abstract Discontinuous Deformation Analysis (DDA) is a Finite Element style discontinuous engineering numerical method. DDA is also an implicit version of DEM. DDA was developed especially for rock stability analysis, which is related to safety of personals and engineering projects. Therefore...

..., and shale, as well as folding structural rock control. Therefore, drill and blast techniques were used to excavate and develop the road cut slope. As a result, three sections,19, 20, and 21, with both sides of the road slope were chosen for evaluation. The stability of rock slopes is considered important...

... Abstract The roof stability of karst caves is of great concern for engineers when they are conducting construction work in karst areas. Accurately determining the factor of safety (FOS) of the cave roof against instability is generally difficult because of the uncertainties involved...

... Abstract To realize the harmonious unification of safety and economy when designing slopes, we used geological analysis and performed a qualitative evaluation to investigate the controlling factors affecting slope stability. The finite element strength reduction method (SRM) and traditional...
