摘要

我国作为一个地震多发国家,近年来多次遭受地震灾害。而大量高度大、基础埋深大、建筑结构复杂的建筑物在近些年内集中建设,对于建筑抗震设计要求越来越高,需要采用数值分析方法辅助抗震设计。本文以北京市丰台区某超高层建筑为例,采用FLAC~(3D)软件建模计算了地震工况下桩基础的变形和速度响应情况,为桩基础的抗震设计提供预测数据。
        As an earthquake-prone country, China has suffered many earthquake disasters in recent years. A large amount of buildings with large height, deep foundation and complex building structure have been built in the last few years, and the higher quality for seismic design of buildings is required. Therefore, numerical analysis method is needed to assist seismic design. Taking a super high-rise building in Fengtai District of Beijing as an example, the deformation and velocity response of pile foundation under earthquake condition are calculated by using FLAC~(3 D) software, which provides the prediction data for seismic design of the pile foundation.
