| Abstract: | This paper describes the content, method and conclusion of
prospecting and studying the fault at the area of Jitimen Bridge site in Zhuhai City. It points out that large scale of tattered belt(about 28m in wide)and verticle drop (about 6m) occurred at F 3 fault crossing to the bridge axis. In the period of Epileistocene. this fault moved repeatedly, which took strik slip as the major motion. But since 22 thousand years it has gradually tended to stable and it was not very active in the period of Holocene epoch. |
