| 摘 要： | 对西冶、五胜流动短水准观测资料进行了分析和异常成因的探讨。认为1998年9月至2000年6月出现的异常变化，是1998年降雨量增大导致断层之间摩擦力减少，在区域应力背景增强的情况下出现的断层蠕滑活动，而不是环境、降雨、地下水位等干扰因素引起的水准点标志升降。

| Abstract: | In this paper, the anomaly of mobile short leveling measurements in Xiyie and Wusheng areas is analyzed and the cause for anomaly is discussed. It is thought that the anomaly from September, 1998 to June, 2000 was creeping slip of the fault because there was the rain-fall accretion in 1998 and friction force between faults was decreased.Thus The creeping slip of the fault appeared when regional stress grew. The anomaly had nothing to do with the elevation and subsiderce of the leveling points caused by environment,rainfall,ground water level, etc. |
