以碾压混凝土坝防渗设施工程造价为目标函数 ,以容许渗透压力、渗流量等要求为约束条件 ,建立了混凝土防渗面板、坝基帷幕灌浆、坝体及坝基排水设施等防渗设施的优化设计数学模型 ;并以龙滩碾压混凝土坝为工程实例 ,以有限元法为基本数值方法 ,采用近似方法对防渗设施的优化设计数学模型进行了求解 ,得出了该工程防渗设施的设计方案
Taking the construction cost of seepage control facilities of RCC dam as an objective function, the impermeable facilities such as concrete seepage control panels, curtain grouting at dam foundation, dam foundation and drainage facilities at dam foundation are set up under the constraints of permissible seepage pressure and seepage volume. The mathematic model is designed. Taking Longtan RCC dams as an example, finite element method is taken as the basic numerical method to solve the optimal design mathematical model of seepage control facilities by the approximate method. The results show that the seepage control facilities Design
