摘　　要：目前我国中低速磁浮交通建设项目较少,设计经验相对薄弱,在设计过程中造价往往难以控制。针对中低速磁浮交通项目,做到既满足项目功能需求又能达到造价最优是业界面临的难题。依托我国某中低速磁浮项目,对该项目中造价控制的主要影响因素进行全面分析。结合中低速磁浮交通的特征,从不同线路敷设方式、车站站间距、车站规模、区间桥梁结构、轨道工程、机电系统、车辆基地等方面通过对比提出优化措施,形成一套系统的工程造价控制参考体系。结果表明:通过合理确定站间距、增加路基敷设长度,以及控制车站规模能有效降低工程造价;桥梁墩柱尺寸优化及并置轨道梁的选用可节约大量建筑材料;竞争性招投标,以及标准化、模块化的轨排研究与设计是轨道工程造价控制的关键;机电系统设计中应充分运用价值工程的理念;应对车辆基地总平面及竖向布置设计进行有效优化。Currently,China has relatively few medium-low speed maglev transit construction projects,causing relative lack of design experience,and difficulty in cost control through design process.For medium-low speed maglev transit project,how to meet project function demands with optimal cost is an industry-wide challenge.Based on a medium-low speed maglev transit project in China,the main influencing factors of cost control in the project are comprehensively analyzed.Considering characteristics of medium-low speed maglev transit,optimization measures are proposed from different aspects such as different line laying modes,station spacing,station size,interval bridge structure,track engineering,electromechanical system and vehicle base,forming a systematic reference system for cost control.Results show that measures including reasonable station spacing,increasing subgrade laying length,and controlling station size can effectively lower project construction cost;bridge pier size optimization and selection of parallel track beams can save a significant amount of building materials;competitive bidding,standardized and modularized track design are key factors in controlling the cost of track engineering;the concept of value engineering should be fully utilized in electromechanical system design;and vehicle base layout design should be optimized in both general layout and vertical arrangement.
