摘要

九江瑞昌5.7级地震是江西省近代以来强度最大、破坏最为严重的一次地震。由于震区地质条件复杂,房屋抗震性能差,再加上震源浅因而造成了大量民房的毁坏。在地震现场科学考查的基础上,针对灾区主要结构类型房屋的破坏情况,从灾区地震地质环境、不同结构类型房屋的分布情况和震害特征,对不同结构类型房屋的破坏成因作了较为客观的分析与总结。
The MS5.7 Jiujiang Ruichang earthquake is the strongest and the most damaged earthquake recently in Jiangxi Province. It caused a large number of building damages,not only due to the complex geological conditions and the poor conditions of geology,soft soil,surface water,underground karst,but also due to the strong intensity and shallow hypocenter of this earthquake. This paper makes a primary investigation and summary for the destroy instances of the main types of buildings in the disaster area. The distribution and earthquake damage features of the geological environment and different types of houses in the disaster area are introduced. In addition,the structure characteristics and anti -earthquake capabilities of different types of buildings are analyzed and summarized objectively.
