广西南部农村群体建筑抗震能力评价

Evaluation of seismic capacity of rural group buildings in southern Guangxi

广西近年来陆续发生3次5级以上中强地震,给当地农村建筑造成不同程度的破坏。为掌握广西南部地区农村民居抗震能力现状,对广西3个市中的6个县(区)12个村122栋农村房屋开展了抗震能力详细抽样调查。本文分析了调查区不同结构类型建筑比例和现状,指出农村房屋在抗震设计、构造和施工中存在的不足,利用改进的区域房屋抗震能力快速评价方法,对各个村的总体建筑抗震能力进行评价,提出增强房屋抗震性能的意见和建议。结果显示:2个村的总体房屋抗震能力为“较强”;10个村为“一般”。

In recent years,three moderate and strong earthquakes of magnitude 5 or above have occurred in Guangxi,which have caused varying degrees of damage to the local rural buildings.In order to understand the current situation of aseismic capacity of rural dwellings in southern Guangxi,a detailed sampling survey was carried out on the aseismic capacity of 122 rural houses in 12 villages of 6 counties in 3 cities of Guangxi.This paper analyzes the proportion and present situation of different structural types of buildings in the survey area,points out the shortcomings in the anti-seismic design,construction and construction of rural houses,Use the improved method for rapid evaluation of seismic capability of regional buildings,evaluates the overall anti-seismic capacity of buildings in each village,and puts forward suggestions and suggestions to enhance the anti-seismic performance of buildings.The results show that the overall housing seismic capacity of 2 villages is"strong",and 10 villages are"average".
