With the rapid development of cities and continuous progress in rail transit construction, the alignment of newly-built rail transit projects has become increasingly complex. It is inevitable for transition curves at stations in central urban areas to intrude into the end section of effective platforms. Excessive intrusion of transition curves into the scope of effective platforms will directly lower the speed limit standards for curved track sections, restricting train speed increase and the optimization of the overall line travel time. Against this background, this paper thoroughly analyzes the key influencing factors of transition curve intrusion into the length of effective platforms, and determines the controllable and allowable intrusion length in combination with actual operation conditions. On this basis, this paper innovatively puts forward three optimization schemes, namely sectional arrangement of the superelevation gradient for transition curves, reduction of transition curve length, and reduction of curve radius, to increase curve superelevation and further raise the maximum speed limit of curved track sections. Through comprehensive comparison and selection analysis combined with practical engineering cases, the research draws the following conclusion: the scheme of reducing the curve radius is prioritized on the premise of meeting the requirements of relevant specifications; for sections constrained by engineering conditions, the schemes of sectional arrangement of the superelevation gradient for transition curves and reduction of transition curve length can be adopted as alternative options.

针对中心城区车站缓和曲线过度侵入有效站台端部影响列车提速及全线旅行时间优化问题,深入剖析缓和曲线侵入有效站台长度的主要影响因素,结合运营条件确定其可控允许侵入长度,提出分段设置缓和曲线的超高顺坡率、减小缓和曲线长度、减小曲线半径3种优化方案以提高曲线超高,进而提升曲线线路最高限制速度。经综合比选分析,并结合实际工程案例,得出:在满足规范要求的前提下,优先推荐采用减小曲线半径的方案;而在工程条件受限的地段,则可考虑采用分段设置缓和曲线的超高顺坡率和减小缓和曲线长度的方案。

针对中心城区车站缓和曲线过度侵入有效站台端部影响列车提速及全线旅行时间优化问题,深入剖析缓和曲线侵入有效站台长度的主要影响因素,结合运营条件确定其可控允许侵入长度,提出分段设置缓和曲线的超高顺坡率、减小缓和曲线长度、减小曲线半径3种优化方案以提高曲线超高,进而提升曲线线路最高限制速度。经综合比选分析,并结合实际工程案例,得出:在满足规范要求的前提下,优先推荐采用减小曲线半径的方案;而在工程条件受限的地段,则可考虑采用分段设置缓和曲线的超高顺坡率和减小缓和曲线长度的方案。

With the rapid development of cities and continuous progress in rail transit construction, the alignment of newly-built rail transit projects has become increasingly complex. It is inevitable for transition curves at stations in central urban areas to intrude into the end section of effective platforms. Excessive intrusion of transition curves into the scope of effective platforms will directly lower the speed limit standards for curved track sections, restricting train speed increase and the optimization of the overall line travel time. Against this background, this paper thoroughly analyzes the key influencing factors of transition curve intrusion into the length of effective platforms, and determines the controllable and allowable intrusion length in combination with actual operation conditions. On this basis, this paper innovatively puts forward three optimization schemes, namely sectional arrangement of the superelevation gradient for transition curves, reduction of transition curve length, and reduction of curve radius, to increase curve superelevation and further raise the maximum speed limit of curved track sections. Through comprehensive comparison and selection analysis combined with practical engineering cases, the research draws the following conclusion: the scheme of reducing the curve radius is prioritized on the premise of meeting the requirements of relevant specifications; for sections constrained by engineering conditions, the schemes of sectional arrangement of the superelevation gradient for transition curves and reduction of transition curve length can be adopted as alternative options.
