| 摘 要： | 利用边界积分方程法对土质边坡失稳地球物理模型的视电阻率进行了系统数值计算，研究了土质边坡失稳的电阻率响应特征，揭示了边坡从稳定一失稳演化过程的电阻率变化规律，从而实现了边坡失稳的电阻率响应特征的提取。这些特征信息的获得为利用电法勘探方法探测土质边坡失稳的滑动面或结构面位置提供了依据，同时为实时观测，预测预报土质边坡失稳提供了理论支撑。

| Abstract: | Calculating systematically the apparent resistivity of geophysical model relating to soil slope instability based on boundary integral equation, it has researched the resistivity responding characteristics reflecting soil slope instability, and revealed the variation rules of resistivity with the slope changing from stability to instability so as to make the resistivity responding characteristics of soil slope instability been obtained. According to the obtained characteristics, the slip plane and structural plane of instable soil slope can be determined by the application of electricity prospecting, as well as the real-time observation and forecasting soil slope instability can be made with more theoretical support. |
