开挖蓄水条件下边坡破坏机理及稳定性研究
Failure mechanism and stability of slope under excavation and water storage
摘要
Abstract
In order to investigate the effects of important buildings and structures on the upper part of the slope under excavation and water storage,physical experiments are used to explore the changes of stress,deformation,surface settlement and pore water pressure of the slope rock mass in the process of excavation and water storage.Meanwhile,deformation,failure characteristics and laws of the slope and fault tectonic zone under excavation and water storage are analyzed.The results shows that excavation will lead to the redistribution of the stress of the rock mass,the stress of slope surface will change greatly,and the upper wall rock mass will have a relative dislocation trend along the fault fracture zone under the action of self-gravity during excavation.At the initial period of water storage,the surface is compacted by the dynamic and static water pressure,the internal pore water pressure increased,the slope is deformed to the free side,and also settlement trend appears at the top.The results can provide a basis for the prevention and control of landslides in high and steep open-pit coal mines.关键词
