Abstract: Based on some destructions of Shuangshusi reservoir during Minle earthquake, Ground Penetrating Radar is used to study the slide tendency of high slope at spillway right bank. The detecting mechanism of slide disease and typical radar image characteristics are analyzed. The location and degree of latent slide tendency of reservoir high slope after earthquake are diagnosed. The detecting results indicate that the GPR be carried out the detection and evaluation of slide tendency of reservoir high slope in China westward loessland.

摘要： 本文以甘肃省民乐地震时受到一定破坏的双树寺水库为对象，对水库溢洪道右岸高边坡震后滑动趋势进行了探地雷达探测和研究，分析了水库滑坡病害的探测机理和典型雷达图像特征，诊断了水库受震后内部滑动的位置、程度和趋势。研究表明，探地雷达可用于西部黄土地区水库高边坡滑坡趋势的探测和评估。
