摘要
坝体渗漏问题是国内现有土石坝中的普遍现象,约25%的大坝失事源于渗流,由多孔介质土料建造的均质土坝较多建设于上世纪,在土体级配效果不佳、选材标准要求不严格、孔隙碾压处理不到位的情况下,所修建的均质土坝往往在渗流稳定性方面存在一定缺陷,导致坝坡滑移、坝体裂缝、流土、管涌等一系列问题时有发生,相关单位有必要重视对均质土坝稳定性的分析与加固处理工作。以某水库均质土坝项目为例,分析了土坝稳定性与加固处理方案。
Seepage of dam body is a common phenomenon in existing earth-rock dams in China, about 25% of dam failures are caused by seepage. Homogeneous earth dams constructed from porous medium soils were mostly built in the last century. In the case of poor grading effect of soil, poor material selection criteria and poor pore compaction treatment, the homogeneous earth dam built often has certain defects in seepage stability, resulting in a series of problems such as dam slope slip, dam body cracks, flow soil, piping and so on. It is necessary for relevant units to pay attention to the stability analysis and reinforcement treatment of homogeneous earth dams.Taking a homogeneous earth dam project of a reservoir as an example, this paper analyses the stability of earth dam and reinforcement treatment scheme.
