摘要
防渗系统是土质堤坝薄弱的部分之一,如何在防渗墙的抗震能力和建造费用之间找到一个较好的平衡点,一直是工程界关心的重要问题。提出了高聚物防渗墙抗震性能安全系数的概念,将基于图解法的多目标优化方法应用于高聚物防渗墙优化设计。以地震作用下高聚物防渗墙抗震性能好和工程造价低为目标,建立了高聚物防渗墙抗震安全性和经济性为组合的优化模型,进行了高聚物防渗墙墙体材料密度优化设计,为地震作用下高聚物防渗墙密度优化提供了一种简洁和直观的优化计算方法。
Anti-seepage system is one of the weak parts of earth dikes and dams. How to balance the seismic capacity and the cost of anti-seepage wall is an important issue in the engineering. The safety factor of anti-seismic property for polymer anti-seepage wall was proposed in the paper. The multiple-objective functions optimization methods based on graphic method was used in the optimization design of polymer anti-seepage wall. With the purpose of good anti-seismic property and low cost, the optimization model which combines seismic safety with economical effi- ciency was established and the density optimization design of polymer anti-seepage wall was conducted. The optimization design of multiple-objective functions based on graphic method for polymer anti-seepage wall provides a con- cise and visual method for the density optimization design of polymer anti-seepage under seismic loads.
