某露天煤矿残余水治理排水管涵方案比选

Scheme comparison and selection of drainage pipe culvert residual water treatment in an open-pit coal mine

对超高松散物料内排土场下原岩开挖+混凝土盖板方案和格宾笼+混凝土涵2种方案进行FLAC3D三维地质建模和数值模拟分析,根据数值模拟结果对比分析2种方案的混凝土不均匀竖向变形、软岩小主应力、混凝土小主应力等,进行对比得出最优结果。

FLAC3D three-dimensional geological modeling of the original rock excavation and concrete cover slab scheme and the latter cage and concrete culvert scheme is numerically simulated and analyzedbased on the innerdump of super-high loose material.According to the numerical simulation results,the non-uniform vertical deformation of concrete,small principal stress in soft rock and small principal stress in concrete of the two schemes are compared and analyzed,and the optimal results are obtained.
