【摘要】 通过岩体结构调查、渗透张量计算和压水试验研究岩体渗透性能。结果发现,基岩裂隙潜水活跃带距地表70m,是有毒元素向河流迁移的活跃通道,须采取河流改道、防渗等应急措施。地下水在岩体中的渗透以垂直方向为主,水平方向较小,总体上对工程有利。更多还原

【Abstract】 The rock permeability is studied by means of rock structure investigation,permeability tensor calculation and water pressure test.The results show that the bedrock’s zone with active fissure water,70 meters deep,is the active channel of toxic elements to the river.So emergency measures should be taken like river diversions or seepage prevention.Groundwater seeps in the rock much more in vertical direction than in horizontal direction,which is favorable to engineering on the whole.更多还原
