| 摘 要： | 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。

| Abstract: | Taking Tacheng concrete face rockfill dam (CFRD) built on the deep overberden in Jinshajiang River for an example, three-dimensional finite element calculation was conducted to study the stress and deformation of anti-seepage system and joints, which the anti-seepage system of the dam adopted connecting plate type and 200 m height of CFRD foundation built on the 100 m deep overburden. And then the feasible schemes are analyzed. Compared with similar dam, the results show that the stress and deformation state of each impermeable structure and joints were reasonable; In three schemes, the third one is the optimum scheme because the shear deformation of the joints in the anti-seepage system is the minimum. |
