【摘要】 应用应力摩尔圆方法,探讨了断层能动度与构造应力方向和断层面几何特征的关系,并与断层活动速率对比分析,将断层失稳度定量化。最后结合地震时间逼近度,求出了断层地震危险度的定量指标,将理论模型应用于渭河盆地南缘断层,取得了较好效果。更多还原

【Abstract】 The relation based on the method of Mohr stress circle. which if that between the activity of fault and the direction of tectonic stress and geometric characteristics of fault plane, has been discussed in this paper. The fault instability can be quantified to compare the activity of fanlt with fault active velocity. Finally, the quantitative index of earthquake risk of fault is obtained to combine with time approach rate of earthquake.更多还原
