| 摘 要： | 利用相关原理,对砂土液化发生机制进行分析,建立液化临界超静孔隙水压力随地震持续时间及埋深等因素变化的关系,以此作为液化临界孔压判别模式。用该判别模式对唐山沿海地区砂土液化特征进行分析,经实际资料对比,证明该模型合理可行。

| Abstract: | The Genesis mechanism of the liquefaction of sand is analyzed herein with the relevant principle，and then the variation relationship between the excess pore water pressure of liquefaction and the factors such as seismic duration and buried depth is established and taken as the mode of judging the critical pore pressure as well. The characteristics of the sand liquefaction within the coastal region of Tangshan are analyzed with this judging mode. Through a comparison with the actual data，it is demonstrated that the model is reasonable and feasible. |
