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.
