WebThe soil failed retrogressively from the lower to upper slope. At t = 5 day, the shear failure surface began to develop at the soil–bedrock interface at the bank slope of Taozi gully. Meanwhile, the maximum displacement was observed at the front edge (Fig. 7 d). The deviatoric strain also began to present at the scarps along the slope profile ... WebAs discussed above, during shear, depending on the stress conditions and void ratio, soils have the potential to develop positive or negative shear-generated “excess” pore pressures. If loading is faster than those excess pressures can dissipate, undrained strengths will usually control short-term stability. From how hard is it to play trombone
