摘要
2013年8月30日13时27分30.3秒乌鲁木齐市发生5.1级地震,该地震的微观震中位于乌鲁木齐市中心繁华地段,属于典型的城市直下型地震。乌鲁木齐市震感强烈,周边的昌吉市、五家渠市等有明显的震感。本文介绍了此次地震发生的地震地质环境背景,并根据震害调查资料及乌鲁木齐烈度速报台的记录给出了地震影响场分布结果,在此基础上重点分析了破坏建筑物的震害特征,对未来乌鲁木齐城市抗震设防工作提出了建议。
At 13: 27: 30. 3 on August 30,2013,a magnitude 5. 1 earthquake occurred in Urumqi. Its micro epicenter was located in downtown Urumqi,which is known as earthquakes occurring directly beneath the city. The habitants of Urumqi had strong feeling of this earthquake,and the people in circumjacent cities,such as Changji,Wujiaqu also felt shaking. In this paper,the seismotectonic background of the earthquake is introduced briefly.And according to the seismic damage,the distribution of seismic intensity of the quake is given. Then characteristics of the damage on buildings are analyzed. Some proposals for improving seismic resistance of buildings are put forward.
