摘要
本文利用西南地区原地应力测量数据结合测点附近主要活动断裂几何要素、断裂微量位移及其附近M_S≥5.0级地震能量释放等资料进行了综合分析,表明地震能量释放相对偏低、断裂微量位移也相应较小的测区,断裂面τ/σ_n值较高;反之则出现相反的情形。
In this paper, the authors have made a Comprehensive analysis used on the data of in-situ stresses measurement combining with the geometry factors for main active faults and the data of micro-dis-placement and the earthquake energy release of Ms≥5. 0 near the active faults. It was shown that the τ/σ2, quantity was higher at the region with lower earthquake energy release and micro-displacement for rift, but it was the opposite situation the other way round.
