物探方法在探测隐伏断层中的应用

在地震安全性评价和工程场地勘探中，探明活动断层是一项必做的工作；而探明活动断层的方法选择要因地制宜，经济科学。笔者运用电剖面法、地震反射法、地质雷达法以及断层气测量方法，对珲春地震小区内含煤盆地中的发震断裂构造进行了研究，断层气测量法是一种探测(除水域、稻田以外的地区)隐伏断层的简捷、快速、可靠、经济的方法。

Applying Geophysical Methods for Detecting Buried Faults

The detecting active faults is necessary for estimation of safety affected by possible earthquake and for architectural engineering. Therefore,it is important to choose a better geophysical method for the detecting work. The authors applied some geophysical methods, including the electric section,seismic reflection,GPR,and the measure of fault gas,for studying the fault structures causing earthquake in the coal-bearing basin of the Hunchun earthquake zone,and got good results. We found that the measure of fault gas is a simple,fast,credible and economic method used for detecting buried faults in the places excepting for the watered and paddy areas,among the geophysical methods applied.
