| 摘 要： | 利用安宁河-则木河断裂带上的跨断层流动形变资料,计算了断层活动累积量,定量研究了断层在不同时间段内的活动特征,然后采用断层活动总体状态参量R(t)值对断层总体活动特征进行了综合分析,探讨了其与地震活动的关系。结果表明:安宁河-则木河断裂带在观测期内以左旋走滑活动为主,兼具逆冲活动;断层总体活动状态参量R(t)显示,断层整体活动的不稳定性与强震有关,断层活动不稳定时,地震活动也较强烈。

| Abstract: | By using the observation data of fault-crossing mobile sites in Anninghe-Zemuhe fault, we calculated the cumulative amount of vertical lifts, analyzed the current faulting characteristics in different time quantitatively, and then used R(t) to describe the overall faults activity level quantitatively. Our results show that Anninghe- Zemuhe fault is left-lateral strike slip with thrusting activity; integrated parameter R(t) of fault activity show that instability of the overall faults activity has a relatively close relationship with the occurrence of strong earthquakes, and when the fault activity is unstable, seismic activity is more intense than before. |
