在软粘土地基稳定分析时,必须使地面堆荷不致有引起软土地基发生剪切破坏的危险。土体承受荷载以后,将产生超静水压力。由于粘性土的渗透性很差,在正常堆料速率下加荷后的瞬时排出的水量很少,因此堆料刚完成时,可以用不排水试验来求得土 In the stability analysis of the soft clay foundation, it is necessary to make the ground load not cause the risk of shear damage to the soft soil foundation. After the soil is loaded, it will generate an excess hydrostatic pressure. Because the permeability of clay soil is very poor, the amount of water discharged instantaneously under normal loading rate is very small, so when the stock is just completed, the undrained test can be used to obtain the soil.
