摘要： 深入分析某工程边坡五个监测点的监测资料，通过重点研究降雨对工程边坡变形的启动时间和缓和收敛时间的影响，以及分析变形位移规律，得出的主要结论为：工程边坡变形的启动时间和缓和收敛时间明显滞后于降雨量大且集中的时段，滞后大约20天；降雨不仅引起了工程坡体位移量值的突变，而且使工程坡体位移产生了明显的趋同性。

Abstract: The deformation monitoring data of the five monitor points in slope engineering is studied thoroughly, especially the influence of startup and reduce convergence time of slope deformation initiated by rainfall, and the deformation law is analyzed. Results show that both of the startup time and the reduce convergence time are obvious hysteresis, which lags the time section of heavy and intensive rainfall about 20 days. Furthermore, rainfall not only triggers the slope displacement's mutation, but also makes its obvious development trend.
