浅层地震勘探在工程选址中的应用及断层活动性鉴定

摘要

石油地质资料显示，沧州某拟建工程厂址地下深部展布有3条断层，通过浅层地震勘探确认，其中2条断层埋深较深，另1条断裂埋藏较浅，延伸至近地表。通过跨断层钻探、地层年代测试等详实工作，鉴定了该断层的活动性，依据有关研究成果评价了断层对工程的影响，为断层确认及其活动性鉴定在工程中的实际应用提供借鉴。%Petroleum geological data show that ,there are three deep faults in the engineering site of Cang‐zhou .The detailed work contained the shallow seismic exploration ,drilling and formation age test of fault overlying Quaternary strata .The activity of the fault is identified and the influence of the fault to the engi‐neering is evaluated .It provides a typical example for the practical application of fault activity identification in the important engineering location .
