摘要(Abstract)：
相比滑坡灾害监测的传统方法，电阻率法监测方法具有大范围监测地下结构和含水性等信息的优势。在探讨了时移电阻率法滑坡监测的方法和原理的基础上，以张家峁滑坡为原型，建立了降雨前和降雨后的滑坡地质地球物理模型，开展了时移电阻率法滑坡监测的三维数值模拟计算及现场试验。数值模拟结果表明：时移电阻率法监测结果可以较好的反映滑坡结构和含水性变化情况，降雨后滑动带相对滑坡体和滑坡床为相对低阻特征，时移监测结果相比单次探测结果更有利于对滑动带的定位。现场试验结果表明：时移电阻率法监测可以查明滑坡结构、获取地层含水性分布特征和变化情况，提高对滑动带的定位精度，为滑坡监测、预警预报和工程治理提供理论和技术支撑，有效降低滑坡灾害风险。
