摘要
对于高面板堆石坝,填筑分期断面形状和尺寸不仅关系到坝体填筑强度、填筑速度,同时也与坝体沉降变形控制紧密相关。本文综合考虑施工程序、施工强度等施工组织要素和坝体变形控制,构建了高面板堆石坝填筑分期断面优化模型,该模型可以对填筑断面的形状和尺寸进行优化。通过对传统粒子群算法的改进,提出了填筑分期断面优化的异质粒子群算法。工程案例分析表明:该方法具有较好的稳定性和收敛性。
Shape and size of the staged filling section of a high concrete-faced rock-fill dam （CFRD） are not only closely related to filling strength and filling speed of dam body, but to dam settlement deformation control. This study develops an optimization model of high CFRD staged filling section, considering factors of construction organization and settlement control, such as procedure and strength of dam construction. This model can be used to optimize the shape and size of filling section. The heterogeneous particle swarm optimization （HPSO） algorithm is presented to optimize shape and size of the filling-stage section based on improving traditional PSO. Application of this new algorithm to analysis of an engineering case demonstrates its numerical stability and convergence.
