摘　　要：抽水蓄能电站上库填筑工程量较大,为了合理划分填筑阶段、规划各阶段填筑工程量及填筑面貌,需要对上库填筑进行分期分区优化研究。上库填筑由坝体填筑与库底填筑两部分组成,填筑过程受多种影响因素和控制条件的制约,各部分对填筑料物的需求量与质量要求不同,各种材料的施工作业面面积随高程的变化规律也不一致。考虑施工作业的阶段特性,使用填筑区期望强度系数对各时段填筑区的填筑强度进行协调,通过建立上库填筑分期分区优化模型,利用异质粒子群算法优化求解得到最优的分期分区填筑方案。将该方法应用于华东地区某抽水蓄能电站上库填筑工程中,对计算结果进行分析验证了模型和算法的有效性。The filling volume of pumped storage power station upper reservoir construction is huge.In order to obtain a rational scheme of filling volume and visage of each filling period,a study on upper reservoir staging and zoning is carried out.Upper reservoir filling is consist of dam filling and basin filling,the filling process is influenced by many factors and control conditions.The requirement of filling material qualities is different in each part,and the change rules of construction operation area are not consistent when the elevation increase.In this paper,the construction characteristics in different period is considered,and the expected strength coefficient of filling zone is used to adjust the filling intensity of filling zones in each period.Consequently,the staging and zoning models are established,and the heterogeneous particle swarm algorithm was used to select the optimal plan.This method is applied in a pumped-storage power station in Eastern China.The results show that the model and algorithm are effective in the real construction projects.
