- 摘要:
- 鄂西某电站右坝肩中上部缓倾坡内的层状岩体深部,存在顺层发育的岩溶坍塌堆积物,该坍塌堆积层厚约2～3m,坍塌半径约为20～30m,主要由白云质灰岩碎块、泥砂物质和钙质胶结物组成.它们的存在,可能会构成影响坝肩岩体渗透稳定性的控制性边界条件之一,因此,针对该溶蚀坍塌层展开渗透试验研究,从机械潜蚀和化学潜蚀两个方面阐述其渗透变形特征,进而定性地评价其对工程的影响.
- Abstract:
- Some solution collapse accumulation develops flow the layers,which are gently inclinding to the inner side or slope,in deep rock body of the left shoulder of a dam in West Hubei.With 2～3 m thickness and 20～30 m collapsing radius,the solution collapse layer mainly consist of shivers of dolomitic limestone,bedload and calcareous cement.It is the solution collapse layer that may forms one of the controlling borders which impact the seepage stability of rock body in dam’s shoulder.Filtration tests are carried out aim at the solution collapse layer.The features of seepage deformation were expatiated from two aspects:physical suffosion and chemical suffosion.Then its effects on the engineering were estimated.
