摘要
探讨裂纹的扩展是否会导致地震的判断方法,分析Ⅱ型裂纹在张开与闭合情况下的不同扩展规律,讨论断层等结构面的分布形态对地震序列的影响等方面的问题。
The different crack propagation behaviors for open or closed model Ⅱ crack are analysed theoretically and experimentally. Meanwhile, the problems of whether crack propagation will cause earthquake and how the structure plane distribution influences earthquake series are investigated.
