摘　　要：在对东津水电站溢洪道左岸高边坡变形监测资料分析时发现,2003年6月的抗剪桩水平位移过程线出现了较大幅度的跳跃。为查明原因,保证高边坡的稳定运行,分别采用统计模型和分形几何方法进行了成因分析,并认为造成该监测值发生突变的主要因素是强降雨。Through the deformation monitoring data analysis for the steep slope of spillway left-bank in Dongjin Hydropower Station, a big jump of horizontal displacement of the shear-resistant pile in June 2003 is noticed. In order to find out the causes and make sure the stability of the steep slope, statistical model and fractal geometry theory are used in the cause analysis. It is shown that the jump of horizontal displacement is mainly caused by strong rainfall.
