摘要：

优化地铁线路纵断面设计方案可降低列车运行能耗与风井建设成本.本文以盾构法施工的地铁地下线为研究对象，考虑地铁设计规范约束与实际施工条件，建立以列车双方向运行能耗与风井成本之和最小为目标的线路纵断面优化模型.采用模拟退火与遗传算法的组合方法求解.广州地铁14号线案例分析证明，与实际方案相比，本文模型所得优化方案节省 2.65％的总成本.与仅考虑站站停模式下的纵断面优化方案相比，本文模型所得方案在快慢车总能耗方面更优，说明考虑停站方案进行纵断面优化的必要性.

Abstract:

The optimization on vertical alignments of subway tracks reduces the energy consumption of train movement and the construction cost of ventilation shafts. Focusing on the subway lines constructed by theshield tunneling method, this paper establishes an optimization model on the track vertical alignment with the objective of minimizing the weighted sum of train energy consumption and ventilation shaft cost. The model takes various design criteria and practical construction requirements into consideration. The simulate anneal and genetic algorithms are applied to solve the proposed model. The case studies on Guangzhou Metro Line 14 indicate that the optimized track alignment reduces the total cost by about 2.65%in comparison with the practical alignment. Moreover, the proposed model outperforms the previous models considering trains stopping at every station only in energy saving, which indicates the train stop patterns should be considered in the optimization on vertical alignments of subway tracks.

Key words: urban traffic, rail transit, track vertical alignment, train energy consumption, ventilation shaft cost
