Application of Shallow Seismic Reflection Technology to Detecting Concealed Active Faults

隐伏活动断裂对工程建设的危害是巨大的,隐伏活动断裂的勘察与防治是工程建设和运行安全的关键。本文以某大型油库为工程实例,针对隐伏活动断裂勘察技术手段和技术方法进行了系统的探讨,并对隐伏活动断裂勘察采用的浅层地震技术线路、数据采集、数据处理、结果解译以及工程地质钻探方案制定等方面进行了深入细致的研究,切合实际地提出了隐伏活动断裂防治措施,很好地解决了工程建设中存在的地质问题,工程实践表明,采取浅层地震勘探和工程地质钻探相结合的综合勘察技术是查明隐伏活动断裂的有效方法,为该地区类似工程建设提供了可供参考的实践经验。

The concealed active faults often have a very bad effect on engineering constructions,so the investigation and prevention are very important.In this paper,taking a large oil depot as an example,the technique of exploring the concealed active faults is systematically discussed.The shallow seismic method,data acquisition,data collection,data process,data interpretation and engineering geological drilling program are also studied in details.Then,the measure of preventing the active concealed faults are suggested,which solves the problems of engineering construction.The result of the practical application in engineering construction proves that the effective method of detecting concealed active faults is to combine shallow seismic exploration with engineering geological drilling.This provides a valuably practical experience for the similar engineering construction in this area.
