Research conclusions:The slope deformation is positively correlatedwith rainfal,l and the largestdisplacementhappens in front edge of the slope, themedium one inmiddle partand the smallone in the rear edge. In the course ofone short and strong rain, the deformation ofslope increased graduallywith the rain. But the deformation still continued to enlarge within 72 hours after the rain stopped, and then it slowly became small afterbecoming the biggest.
