摘　　要：复杂地质隐伏断层探测是地球物理勘测难点之一。本文介绍了高密度电法、浅层地震反射波法、可控源音频大地电磁测深法在北京山前平原隐伏断层综合探测的应用。在北京山前平原复杂地形条件下,综合物探技术方法对隐伏断层的探测具有可靠和成果直观的特点。The detection of buried fault in complex geological environment is one of the difficulties in geophysical survey.This paper gives the application examples of three geophysical exploration methods to reveal buried fault comprehensively in piedmont plain of Beijing.These methods include high-density resistivity method,shallow seismic reflection method and CSAMT measurement.The exploration results of the three methods are analyzed to reveal the buried fault through the drilling data verification.The detection results show that integrated geophysical exploration methods in complex topographical conditions in buried fault detection have great superiority such as reliability,convenience and intuitiveness etc.The combining method of geophysical methods can be used for reference in active buried fault detection in China.
