摘要
在第四纪覆盖区工程场地地震安全评价近场工作中,浅层地震勘探是进行断层探测、断层活动性分析的重要物探手段,结合浅震在常德沅水桥地震安评中的应用实例,归纳分析了该方法在本领域应用的技术特点、技术路线,探讨了物探手段研究断层活动信息的几个问题。
Seismic exploration is an important geophysical exploration method for detecting faults and analyzing fault activity in near-site researches on the seismic safety evaluation of quaternary overburden in construction sites. Based on the application example of seismic safety evaluation at Ruanshui Bridge site in Changde, this paper has analyzed the technical characteristics and the means in the application of the method in this field, and discussed some problems in applying the geophysical exploration method to studying the fault activity.
