| 摘 要： | 结合地质和遥感图像解译资料,以物探方法查找活断层是行之有效的方法。针对单一的物探方法在反演解释中具有多解性的弊端,本文提出以高密度电阻率法为主,浅层地震反射波法为辅的综合物探勘察组合模式。经实际钻探证明,这种综合物探模式对隐伏活断层的勘察是完全可行的,并具有较强的实用推广性。

| Abstract: | The survey of a buried active fault is the primary task of a seismic safety evaluation in Zhangjiakou City, China.Geophysical exploration using geological data and the remote sensing interpretation of data is one of many effective methods for locating the active fault.This study used a comprehensive geophysical exploration model that combined the high-density resistivity method and the shallow seismic method.The faults, which were approximately 100 m deep, were found using the high-density resistivity method.This method provided the electrical properties and electrical structures of the active fault.Shallow seismic exploration is one of the most effective geophysical exploration methods and offers the highest resolution in the detection of active shallow urban faults.It also provides the accurate location and size of a fault and can determine the fault''s strata deformation age and related parameters.The high-density resistivity method can also improve the reliability of the shallow seismic method and the combination of these two methods can determine the fault''s formation properties more accurately.Actual drilling data proved that this comprehensive model is one of the best methods for active fault investigation.It has strong promotional and practical value. |
