摘要
本文依据近年来江苏省茅山地区进行野外调查得到的新资料,对茅山东侧断裂带(简称茅东断裂)的基本特征作了概括和分析,在多种观察资料的约束条件下建立了三维动力学模型,以解释茅东断裂现代运动的力学机制及其与溧阳地震的关系,指出控制断层运动的应力状态是随深度而改变的。最后对有关溧阳地震发生原因的一些力学问题进行了讨论。
The basic feature of eastern Maoshan fault zone has been summarized and analysed in the light of new data acquired from the recent field investigation in Maoshan Prefecture, Jiangsu Province. Under control of multi-observation data, we have established a three-dimentional dynamic model which has been used to explain mechanism of eastern Maoshan fault motion and its relation to Liyang earthquakes. It is demonstrated that the stress state for controlling fault motion varies with depth. Finally, some mechanic problems about Liyang seismogenesis have been discussed in this paper.
