Optimization Design Method for Water-Storing Ponds of Slope-Runoff Interception

以坡面截流蓄水塘坝为研究对象 ,推导了坡面截流蓄水塘坝的挖、填土方量计算公式 ,讨论了在塘坝兴利蓄水容积一定条件下 ,以土方量、蒸发渗漏损失和占地损失最小为目标的优化设计方法 ,建立了多目标非线性规划数学模型 ,并介绍了应用LINGO软件求解该模型的方法 ,最后通过一个算例说明该模型的应用。

Taking water_storing ponds of slope_runoff interception as object of study, the calculation equations of earthwork of excavation and filling are deduced, and the optimization design method with the objectives of minimizations of earthwork, evaporation and seepage loss and land_occupation loss under the condition of fixed_capacity of water storing of pond is discussed. A multi_objective non_linear programming mathematic model is established, the solution method of the model by using software LINGO is introduced, and the application of the model is illustrated with a case study.
