黄河黑山峡大柳树坝址、雅砻江锦屏普斯罗坝址及其他一些水电工程区，在勘探过程相继发现了一种新的地质构造现象——深部裂缝带，并且多出现在我国强震活跃地区和强震发生断裂带上，沿断裂带历史上强震活动频繁；深部裂缝带向地下延伸超过300m，远远超出地表卸荷带的影响深度，故与强地震作用时岩体构造动力效应密切相关；讨论了根据弹性波作用下岩体的动力学响应，阐述了深部裂缝带发生的地震学原因。

In hydraulic engineering, deep-seated rupture zones have been discovered in some dam areas, such as Heishanxia of Huanghe River, Jinpingshan of Yalongjiang River and others. It is a new geological structure phenomenon. deep-seated rupture zones are usually situated in the pleistoseismic generating faults. Historic earthguakes frequently occur along the active structure zone. Deep seated rupture zones are 300 m or more beneath the surface, far exceeding the depth of surface unloading range. They are bound up with the dynamics effect of rock mass during earthquake happening. This paper discussed the seismologic reasons for the occurrence of deep seated rupture zones according to elastic wave kinetics.
