摘要
2005年11月26日江西省瑞昌市与九江县间发生里氏5.7级地震,地震诱发了一系列地质灾害,类型有地面塌陷、地裂缝和砂土液化三类,以地面塌陷较为发育。文章根据地质环境条件、地质灾害发生的时间、空间分布等特征,分析了其与地震的关系。并对次生地质灾害的成因进行了探讨,认为此次地震为次生地质灾害的发生提供了动力条件,瑞昌城区供水井抽水加大了发生地面塌陷的概率。
The earthquake of magnitude 5.7 on the Richter scale take place between Ruichang City and Jiujiang County in Jiangxi Province on November 26, 2005, the earthquake has brought out a series of geological calamities, including collapse, ground crack and sand liquefaction of ground, regard relatively collapsing on the ground as the development. According to geology environmental terms, the time and space distributing characteristic of geological calamity, the relation of geological calamity and earthquake is analyzed, and the cause of secondary geological calamity is discussed.It consider the 11.26 earthquakes have offered power terms for emergence of the secondary geological calamity, the probability of the ground collapses is increased because the water of Ruichang urban supplying well is pumping.
