电阻率横向剖面法及其在隐伏断层探测中的应用研究

Application of Schlumberger transverse profiling method to detecting buried faults

针对两盘无明显断距的城市活动断层难以探测的实际问题,根据断层带电阻率特点,提出了电阻率横向剖面法,在物理模拟和数值模拟基础上,通过现场实际断层或裂隙带的探测结果证明:电阻率横向剖面对两盘无差异断层的探测和定位较常规剖面准确,解决了两盘无明显断距断层的探测问题.

To solve the actual problem that urban active faults without obvious displacement axe difficult to be detected, we propose the Schlumberger transverse profiling method based on resistivity characteristics of faults. Through physical and numerical simulation, the actual detecting results of site faults or broken zones show that the Schlumberger transverse profiling method can precisely locate and detect faults without large displacements, and the detecting effect is better than that based on regular profiling methods. Therefore, this method has solved the problem how to detect a fault without clear displacements on its both walls.
