摘要
我国不同时期地铁规范中关于车辆段最小曲线半径取值随着时间推移不断加大,并逐渐稳定。为证实规范合理可行,在收集国内外有关资料的基础上,从地铁车辆段最小曲线半径出发,剖析最小曲线半径的影响因素,并以工程实例分析最小曲线半径选取的标准,论述最小曲线半径对工程实施和运营的影响。建议在现行车辆条件下应尽量遵守现行地铁规范要求,改善运营条件。同时尽快投入力量研究能适应较小曲线半径的车辆及轮轨。
The tight curve radius in metro car depot stipulated in different periods of time keeps expanding and becomes stable gradually. In order to verify the feasibility of the specifications, the influencing factors of the tight curve radius are analyzed based on the data collected from home and abroad, and the impact of the tight curve radius on the construction is discussed based on the analysis of practical tight curve radius selection criteria. It is suggested that the existing subway specifications should be applied under present vehicle conditions, and operating environment improved and research efforts made to new vehicles and rails suitable for small curve.
