【Abstract】 To solve the actual problem that urban active faults without obvious displacement are 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.更多还原
