| 摘 要： | 分析了砂土液化诱发地面侧移的机理，提出了估计砂土液化诱发地面侧颓废不久位一种新方法。该方法是用饱和砂层中水压力的发展，在每个应力循环内对土壤的抗剪强度进行修正，然后在每个应力循环内应用Ｎｅｗｍａｒｋ刚性愉模型计算地面侧向永久位移，对比计算表明，本文提出的方法在物理机制上更加合理，计算结果与宏观震害现象十分吻合。

| Abstract: | In this paper the Mechanism of the ground lateral displacement caused by liquefaction is analyzed. The New method which is used to estimate the permanent lateral displacement induced liquefaction is proposed,which use the law of pore pressure in saturated sand to revise the yield strenth of soil,and applies the model of Newmark's rigid slid block to calculating the permanent lateral displacement of ground in every stress circle. The numerical results show that the method presented is more reasonable in the physical mechanism,and coincides with macroscopic earthquake damage. |
