山区铁路桥隧工程关键节材要素均衡优化OA北大核心CSTPCD
Equilibrium optimization of key material-saving elements of railway bridge-tunnel engineering in mountain areas
为在经济可承受范围内提升山区铁路的节材性能,提出了一种基于NSGA-Ⅱ的关键节材要素双目标均衡优化方法.首先,以断面超挖、喷射混凝土类型选择、围岩变形预留、桩基扩孔、桩头超封5个桥隧工程关键节材要素为决策变量,以CO2减排量最大、建造成本增加值最小为优化目标,构建山区铁路桥隧工程关键节材要素均衡优化模型;其次,采用带精英策略的非支配排序遗传算法(NSGA-Ⅱ)求出Pareto均衡解集;再次,耦合主客观元素组合的综合赋权法与TOPSIS法对Pare…查看全部>>
In order to improve the material-saving performance of mountain railway within the affordable range,a double-objective equilibrium optimization of key material-saving elements based on NSGA-Ⅱ was proposed.Firstly,taking the five key material-saving elements of bridge-tunnel engineering as decision variables,including section over-excavation,shotcrete type selection,surrounding rock deformation reservation,pile foundation reaming and pile head over-sealing,an…查看全部>>
