摘　　要：为实现对山区铁路桥梁绿色设计要素的协调优化控制,提出一种基于绿色设计要素简化网络的耦合协调度优化调控方法。通过分析并识别山区铁路桥梁绿色设计要素,结合复杂网络理论和要素间的耦合关系,建立要素双层耦合网络,依托节点综合重要度和关联度对耦合网络“瘦身”。以耦合协调度最大化、“桥梁可持续能力≤环境承载水平”分别作为简化网络的目标函数与约束条件,构建山区铁路“桥梁-环境”简化网络优化调控模型,并针对模型特点设计一种粒子群优化(PSO)算法进行求解。以某山区铁路某特大桥为例,对其绿色设计要素构建耦合简化网络并进行优化调控,结果验证了本文构建的耦合协调度优化调控方法的合理性,可为桥梁绿色设计提供参考。In order to collaboratively and optimally control the green design elements of mountain railway bridges,a coupling coordination degree optimal regulation method based on a simplified network of green design elements was proposed.Firstly,by analyzing and identifying the green design elements of mountain railway bridges,combined with the complex network theory and the coupling relationship between the elements,a two-layer coupling network of elements was established.The coupling network was“slimmed down”according to the comprehensive importance of the nodes and the degree of association.Secondly,with the maximum value of the coupling coordination degree of the simplified network being obtained and used as the objective function,and the“bridge sustainability≤environmental carrying level”as the constraint condition,the simplified network optimal regulation model of“bridge-environment”for mountain railways was constructed,and a particle swarm optimization(PSO)algorithm was designed to solve the model.Finally,based on a major mountain railway bridge,the rationality of the coupling coordination degree optimal regulation method was verified by constructing a coupled simplified network of green design elements for the mountain railway bridges and carrying out the optimization analysis.The method can provide a reference for green design of bridges.
