由于液化发生在动荷载下孔隙水压力逐渐增加的最后阶段,所以建立孔隙水压力预估方法,对确定土的液化是很重要的。在广泛研究渥太华沙的基础上(石桥勇夫等,1977)作者对均匀周期激震下的饱和砂土建立了预估孔隙水压力上升的公式。但是这些公式未能应用于地震荷载下孔隙水压力的预估。在本文中作者将他们以前得出的预估孔隙水压力的结论,引伸到包括地震的各种荷载类型,并提出数据以便迅速地确定 Since liquefaction takes place at the final stage of increasing pore water pressure under dynamic loading, establishing a method for predicting pore water pressure is very important for determining the liquefaction of soil. On the basis of extensive study of the Otai Warsaw (Shi Qiaoyong Fu et al., 1977), the authors established a formula for predicting pore water pressure rise in saturated sand under uniform periodic shocks. However, these formulas cannot be applied to the prediction of pore water pressure under seismic loading. In this article, the authors extend their previous predictions of pore water pressure to various load types including earthquakes, and present data to quickly determine
