跨坐式单轨与地铁和轻轨工程造价对比分析

Comparative Analysis of Construction Costs of Straddle Monorail Transit,Metro and Light Rail Transit

城市轨道交通投资巨大,本着“量力而行,有序推进,因地制宜,经济适用”的原则,越来越多的城市选择了高架敷设的跨坐式单轨系统,故需要对其造价进行针对性研究以满足项目投资决策需求。结合国内工程实际应用,对地铁、轻轨及跨坐式单轨的工程造价进行剖析,对比其投资构成,总结出工程造价的主要影响因素。研究结果可为决策者选取合理方案、造价人员控制工程造价提供参考。

Tremendous investment is involved in urban rail transit,considering the principle of“Adequate capability,Orderly advancement,Adaptable application,Economic feasibility”,more and more cities are choosing straddle monorail transit system,the construction cost of which requires targeted research to meet the demand of project decision-making of investment and construction.Combined with actual domestic projects,the construction costs of metro,light rail and straddle monorail is deconstructed and analyzed.After comparing investment composition,the main influencing factors of construction cost are summarized.The research results will provide reference for decision makers to select reasonable urban rail transit system and for engineering economist to control project cost.
