摘要:: 通过对2021年5月21日云南漾濞M_S6.4地震开展实地灾害评估调查和震害资料收集,确定灾区人员伤亡情况,建筑物、生命线工程及水利设施震害特征和地震地质灾害特征,给出灾区房屋建筑物震害矩阵,并与省内同级别历史地震震害进行对比研究,对其震害特征原因进行初步分析,最后针对其震害特征提出相关应急处置建议。

Abstract:: We firstly conducted a field investigation of the seismic damage in the area stricken by the Yangbi M_S6.4 earthquake in Yunnan Province on May 21,2021,and acquired the disaster information about casualties,damage to buildings,damage to lifeline engineering and water conservancy facilities,seismogeological hazards,etc.We analyzed the characteristics of the seismic damage in the disaster area.Then we calculated the earthquake-damage matrix of buildings.Further,we compared the earthquake damage by the Yangbi earthquake with the ones by the historical earthquakes with the similar magnitude in Yunnan,and analyzed the characteristics and causes of the earthquake damage by the Yangbi earthquake,and on this basis we put forward suggestions of the emergent disposal of the Yangbi earthquake.
