| 摘 要： | 以《中国地震活动断层探测技术系统技术规程》为依据,结合沈阳、抚顺的实际情况,设计了沈阳市活断层探测的思路。沈阳市活断层探测划分为沈阳、抚顺两个目标区,确定沈阳目标区6条、抚顺目标区2条共8条断裂为目标断层。活断层探测实际上包括初查与目标断层地震危险性评价、详查与主要目标断层地震危害性评价两大阶段的工作内容,具体按照初查阶段目标断层的综合探测、深部地震构造环境探测、目标断层地震危险性综合评价、主要目标断层详细探测、地震危害性评价及活断层信息管理系统建设等几个步骤实施。目标断层的探测手段选取地球化学、地球物理(浅层地震、多道直流电法和探地雷达等)、钻孔探测等,同时结合高分辩率遥感、地震地质调查等方法,各种探测方法和手段根据其探测精度和适宜性分别应用于初查、详查等不同的探测阶段中,探测技术参数的选取在不同阶段也具有差异性,目的是为了实现各个阶段的探测目标。

| Abstract: | In the light of the Stipulation on Technical System for China Earthquake Active Fault Surveying,combining with the actuality of the Shenyang and Fushun city,disigning the thinking of the Shenyang city active fault surveying.It is divided into two TA of Shenyang and Fushun,fixed six and two target faults separately in the Shenyang and Fushun TA.The Shenyang city active fault surveying consists of two phases'work as the primary surveying and the target fault earthquake hazard assessments,detailed surveying and the main target faults earthquake hazard assessments,they are the primary synthetical surveying,seismotectonic environment surveying,earthquake risk assessment on active faults,main target faults detailed surveying,earthquake hazard assessment on active faults and active faults GIS construction,etc.The surveying measures include geochemistrical,,geophysical(shallow seismic investigation,resistivity imaging and ground penetrating radar),drillings,etc.also use of high-resolution remote sensing,seismogeological investigation in this work. |
