摘　　要：该文论述了地震安全性评价工作中对物探的需求,并通过实例阐述了电法联合探测在重大工程场地厂址选择、场地工程地震条件评价、场地隐伏断层探测及活动性评价等方面的应用。实践表明,电法联合探测作为一种无损、价廉、快速的物探方法,综合利用了联合剖面法对异常反应直观与高密度电法资料采集丰富的特点,在工程场地地震安全性评价中有非常实用的价值。This article discusses the demand of geophysical prospecting in earthquake safety evaluation of engineering site and illustrates the application of synthesis electrical prospecting to the selection of engineering site, evaluation of site engineering earthquake conditions and the detection of buried fault. The cases show that the synthesis electrical prospecting comprehensively utilizes the abundant information of high-density resistivity survey and directly shows abnormal body of composite profile and is favorable for data interpretation. It is nondestructive, low-cost and quick-constructed, and it is valued in earthquake safety evaluation work.
