充水式橡胶坝底板的稳定计算参数分析

Analysis on the stability calculation parameter of water filling rubber dam baseplate

充水式橡胶坝作为低水头挡水建筑物,已广泛用于灌溉、防洪、发电、城市景观、美化等工程,对其进行稳定分析具有重要的意义。以住橡胶坝底板稳定计算的竖向及水平向的受力参数未考虑到下泄水流拖曳力对其底板稳定的影响,本文稳定计算参数分析中新增了下泄水流拖曳力和坝顶水体自重,更全面地分析了橡胶坝底板的受力状况,使橡胶坝底板的运行更加稳定、安全,进而为橡胶坝更好地发挥水面效益、美化环境打下了良好基础。

Water filling rubber dam is regarded as low head water retaining structure,which has been widely used for irrigation,flood control,power generation,urban landscape,beautification and other projects.Stability analysis on them has important significance.In the past,the influence of drainage flow drag force on the baseplate stability is not considered by vertical and horizontal force parameters in rubber dam baseplate stability calculation.Drainage flow drag force and dam top water gravity are newly added for stability calculation parameter analysis in the paper.The stress condition of the rubber dam baseplate is comprehensively analyzed.The operation of rubber dam baseplate is more stable and safe,thereby laying a good foundation for developing water efficiency and beautifies environment.
