地下结构震害预测研究综述

Review of Earthquake Damage Prediction for Underground Structures

摘要:

目前城市建筑物震害预测的研究对象主要集中在地面结构。随着地下空间的大量开发利用，地下结构工程数量急剧增多，其震害预测也越来越受到重视。首先对地下结构进行基本分类，并对其地震破坏形式及震害机理进行系统介绍；然后通过梳理近年来地下结构震害预测的研究成果，总结当前地下结构震害预测的常用方法：震害调查统计方法、数值模拟方法、振动台试验方法以及概率分析方法，并指出各类方法的优缺点；最后分析地下结构震害预测研究的发展趋势，为地下结构工程防震减灾工作提供参考。

Abstract:

Currently, research on the prediction of earthquake damage to urban buildings is mainly concentrated on aboveground structures. With the development of underground space and the increasing number of underground structures, prediction of earthquake damage to underground structures is attracting increasing attention. This paper systematically introduces the form and mechanism of earthquake damage to underground structures. Then, we summarize the seismic prediction methods typically used for underground structures based on a review of recent research on the prediction of earthquake damage to underground structures. These methods include the investigation and statistical analysis of earthquake damage, numerical simulation, the shaking table test, and probability analysis. An analysis of the typical applications of these methods and their advantages and disadvantages is presented. This paper can provide support and serve as a reference for future research on the prediction of earthquake damage to underground structures.
