丹江口大坝加高后工作性态分析

Analysis on working behavior of heightened Danjiangkou Dam

丹江口大坝加高工程包括混凝土坝和左右岸土石坝。将工程完工蓄水后的运行监测资料和有限元仿真计算成果进行了对比,分析了混凝土坝的坝体稳定、应力、变形、新老混凝土结合状态及初期工程缺陷处理效果,以及土石坝的坝体变形、渗流场和渗漏等,综合评价了坝体的工作性态。结果表明:丹江口大坝加高后工作性态总体正常,满足正常蓄水要求。

Danjiangkou Dam heightening project includes concrete dam and earth-rock dam on the left and right banks.After the completion and impoundment of the project,the operation monitoring data and the finite element simulation calculation results were compared to evaluate the working behavior of the concrete dam according to the stability,stress,deformation,bonding state of new and old concrete,the treatment effect of initial project defects,and evaluate the earth-rock dam according to its deformation,seepage field and leakage.The results showed that:the working behavior of heightened Danjiangkou Dam was generally normal and could meet the requirements of nor⁃mal water storage.
