摘要
隆盛水库是内蒙古大黑河一级支流拐角铺河上在建的一座中型控制性水利枢纽工程,是调洪蓄水和防止泥沙进入大黑河的重要水利工程。因顺坡向缓倾角节理裂隙及混合岩化作用发育,水库溢洪道右岸高边坡在开挖后修坡过程中,发生了两次大规模滑塌,在收集该地区大量的野外调查资料的基础上,运用FLAC3D软件模拟分析隆盛水库溢洪道高边坡的稳定性,对工程区边坡开挖和修坡条件下的土体变形及位移情况进行模拟计算,获得了边坡在开挖和修坡条件下的最大、最小主应力图和一系列观测点位移图,为工程设计提供参考。
Longsheng reservoir is medium controlling key water-control project, also is the flood water and preventing the sediment into the large key water conservancy project in Heihe. Because of llow-angle joint cracks, the development of migmatization, two large-scale collapse occur in the process of the high slope after excavation on the right bank slope of reservoir spillway. The paper has collected a large number of field survey data in the region, analyzed reservoir spillway slope stability by FLAC3 D. Maximum and minimum principal stress diagram and a series of observation point displacement diagram by simulating calculation under hydro-geologic conditions of slope excavation and slope under the condition of the soil deformation and displacement, provide reference for the engineering design.
