摘要:
黄河黑山峡大柳树坝址区存在大范围的岩体松动破坏现象,其主要特征是岩体应力释放,结构 面张开,密度显著下降。为进一步研究岩体松动的成因机制,在详细调查区域地质背景条件及区域地震 动力作用基础之上,提出了地震动力作用与岩体松动现象的内在联系,通过动力模拟试验进一步证明大 柳树坝址区存在的大深度、大范围岩体松动与历史上该地区发生的强烈地震具有密切关系。因此在目 前的工程地质条件下,一旦发生较大强度的地震活动,坝址区所遭受的破坏程度会更大,对拟建的水利 工程设施将产生严重威胁。
Abstract:
There is a large scale of dynam-relaxed rock mass lies in DaLiushu dam site of Huanghe River.Geostatic stress released、 structural planes opened and density reduced are the main characteristics of dynam-relaxed rock mass. In order to study the de- structive mechanism of the rock mass, geological background conditions and earthquake dynamic effects of the region round Dal- iushu dam site are investigated. The internal relations between earthquake dynamic effects and dynam-relaxed rock mass are con- firmed. A further research to the conclusion is given by the dynamic simulation test. Consequently once a more serious earthquake happened at pesent engineering geological conditions, the rock mass of dam site will be further destroyed. That would be threaten to the new water conservancy at DaLiushu dam site of Huanghe River.
