地震作用下桩基受力特性研究与分析

Study and Analysis on Stress Characteristic of Pile Foundation under Earthquake

目前地震灾害也在世界各地频繁地发生,人类的生命财产遭受了很大的损失,桩基震害作为一种主要的结构震害形式已经引起了人们的重视,因此有必要对在地震作用下土层中桩基础的地震响应进行研究分析。采用有限元方法对地震作用下桩基响应进行研究分析,对桩基的抗震设计具有一定的参考意义。

The earthquake calamity frequently happens now around the world, and the human life and property have suffered a great loss. The earthquake calamity of pile foundation taken as a main structural earthquake calamity type has been paid attention by the people. Therefore, it is necessary to study and analyze the earthquake response of pile foundation in soil stratum under earthquake. The finite element method is used to study and analyze the response of pile foundation under earthquake, which has some referring meaning for the earthquake design of pile foundation.
