| 摘 要： | 地震灾害是自然灾害中较为严重的一种,尤其是对广大的黄土地区。笔者通过ANSYS软件对黄土地区地震时的桩—土相互作用和黄土地区震陷时的桩—土相互作用分别进行了研究,对两者进行比较后得出以下结论:在考虑了震陷时桩的应力和变形有所增大,桩间土体、桩下土体和桩周土体的应力都相应的增大。

| Abstract: | The earthquake is one of natural disasters,which cause damage seriously,especially in the vast loess region. The pile-soil interaction happened during the earthquake and the seismic subsidence in the loess areas is analyzed by FEM,conclusions that stress and deformation of pile is increased on the condition of considering the seismic subsidence,stresses of soil among piles and soil at the bottom of piles and soil around piles are also increased at the same time. |
