摘　　要：在地壳稳定性评价中运用地球物理勘探方法探测隐伏断裂构造行之有效。单一物探方法的使用存在较多局限,综合物探方法的运用体现了其优越性和可靠性。福州市长乐地区通过开展高精度磁法、高密度电法、可控源音频大地电磁测深(CSAMT)法、浅层地震反射法等综合物探方法测量,查明了区内2条北北东向隐伏断裂构造位置及空间分布特征,体现了综合物探方法在断裂构造探测领域的有效性。The application of detection of concealed faults with geophysical methods in the crust stability evaluation works. Compared to a single geophysical method, integrated geophysi- cal methods have been found to provide a reliable industrial application. In the area of Changle county-level city, Fuzhou city, high resolution magnetic method, high density re- sistivity method, controlled source audio-frequency magnetotelluric sound method （CSAMT） and shallow sesimic reflection method were conducted and the positions and spa- tial distribution of the two NNE faults were revealed as well as located. It indicates that the integrated geophysical methods could be a routine tool in detecting faults.
