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 paper discusses the need of geophysical prospecting in seismic safety assessment and illustrates the application of electrical combined detection in site selection of major engineering sites, site engineering seismic condition assessment, site hidden fault detection and activity evaluation through examples. Practice shows that the combination of electrical detection as a non-destructive, inexpensive and rapid geophysical method, the comprehensive utilization of the joint profile method for abnormal reaction visual and high-density data collection of information-rich features in the construction site seismic safety evaluation Very practical value.
