摘要:
［目的］城市轨道交通车辆基地防洪关系到车辆基地及正线运营安全，为有效提高车辆基地防洪能力，需对车辆基地防洪设计要点及措施进行研究。［方法］从设计阶段对影响车辆基地防洪的场坪标高、改移河道设计等要点及注意事项进行详细分析；针对可能出现的大量积水通过车辆基地U型槽进入正线区间造成行车事故的不利情况，开展了防洪措施设计研究，分析确定了出入段线U型槽处为车辆基地防洪关键点；为提高其防洪应急处置能力，从水灾演化规律、监测原则、等级判断及预测、方案设计、智能决策及应急调度等方面进行了防洪及监测方案研究。［结果及结论］在出入段线U型槽位置，采用可移动拼接式防淹挡板设计方案；明确了防淹挡板设计及布置方案、专业接口要点、适用情况；通过设置水位监测点并结合监测融合算法系统、智能决策系统及应急调度指挥系统，构建了出入段线水灾监测、智能决策及应急调度方案，实现灾前、灾中、灾后全过程智能防洪预警及调度指挥。

［Objective］ Flood control in urban rail transit vehicle base affects its safety and the main line operation. To effectively improve the flood control capacity of the vehicle base, it is necessary to study the key points and measures of flood control design. ［Method］ From the design stage, the key points and precautions affecting flood control in the vehicle base, such as field elevation and river diversion design are analyzed in detail. In view of the potential adverse situation when a large amount of accumulated water enters the main line section through the U-shaped groove in the vehicle base, resulting in train operation accidents, research on flood control measure design is conducted, and the U-shaped groove of the inlet/outlet line is identified as the key point of flood control in the vehicle base through analysis. To improve flood control emergency response capacity, the flood control and monitoring scheme is studied from perspectives of flood evolution law, monitoring principle, grade judgment and prediction, scheme design, intelligent decision-making, and emergency dispatching. ［Result & Conclusion］ Movable splicing anti-flood baffle should be used in the U-shaped groove of the inlet/outlet line. The design and layout plan of the anti-flood baffle, the key points of the specialized interface, and the applicable situation are clarified. By means of setting water level monitoring points and combining monitoring fusion algorithm system, intelligent decision-making system, and emergency dispatching and command system, the scheme of flood monitoring, intelligent decision-making, and emergency dispatching for the inlet/outlet line is set up. In this way, intelligent flood control warning and dispatching is realized in the whole course of before, during, and after flood.
