| 摘 要： | 通过室内模型试验，研究了砂土液化对桩基工程的影响，指出了砂土液化时，由于孔隙水压力的上升，土的结构重新调整，桩例摩阻力完全丧失，液化后，由于砂土的固结沉降引起桩侧负摩阻力与地面沉降之间成良好的线性关系，推导并给出了由于砂土液化引起桩的负摩阻力的计算方法。

| Abstract: | This paper deals with the effects of the liquefaction of sand on the pile foundation. Based on a series of tests on the model pile in saturated sand,we find that the lateral resistance of the pile is totally lost with the pore water pressure increased and the structure of soil regulated,and the relation between the negative skin friction and the ground settlement is linear.A computation method has been derived for the negative skin friction of the pile caused by the liquefaction of sand. |
