以金沙江塔城水电站深覆盖层高面板堆石坝为例,采用三维有限元数值方法,研究了在100m级深厚覆盖层上建200m级超高混凝土面板堆石坝坝基与坝体防渗系统的连接采用连接板型式时,坝体各防渗结构及接缝的应力变形情况,并对可行方案进行了优化分析。结果表明,塔城深覆盖层高面板堆石坝各防渗结构及接缝的应力变形与同类坝相比是合理的;三种方案中,设置三块等长连接板时,防渗体系各接缝的剪切变形最小,为最优方案。 Taking the deep overburden high concrete faced rockfill dam of Tacheng Hydropower Station in Jinshajiang as an example, this paper studies the seepage control system of dam foundation and dam of 200m super high concrete face rockfill dam with 100m deep overburden by using the three-dimensional finite element numerical method Of the connection using the connection plate type, dam seepage control structures and joints of the stress and deformation, and the feasibility of the program was optimized. The results show that the seepage control structures and the stress-strain of joints in Tacheng deep overburden high-face rock-fill dam are reasonable compared with that of the same dam. In the three schemes, when three equal-length connecting plates are installed, Seam shear deformation of the smallest, the best solution.
