针对广州地铁十一号线如意坊站缓和曲线最小半径及曲线超高设置超过《地铁设计规范》规定的问题,对地铁站台最小曲线半径、曲线超高以及缓和曲线侵入站台长度等控制因素进行总结分析。通过对站台边缘与车门门槛最大间隙值、站台门与车门最大间隙值、缓和曲线长度、未被平衡离心加速度值、横向加速度最大值、站台范围内车辆倾斜度、车辆地板面与站台面高差值等控制性指标进行验证核查,结果表明如意坊站站台缓和曲线曲率半径小于规范最小值及曲线超高设置大于15mm实际可行,并在节约投资与工期方面取得较好效果,为后续类似工程设计分析提供参考。

[Abstract]
In order to solve the problem of the minimum radius of transition curve and the superelevation in RuYiFang station of Guangzhou Metro Line 11 exceed the provisions of 《Code for design of metro》,The controlling factors of the minimum curve radius, the superelevation and the length of the transition curve into the platform are summarized and analyzed.We checked and verified the Maximum clearance between platform edge and door threshold、the Maximum clearance between Platform Screen Door and train door、the length of the transition curve、the unbalanced centrifugal acceleration、the Maximum transverse acceleration、the inclination of trains within the platform range、the height difference between train floor and platform surface,The results show that it is the curvature radius of the transition curve is less than normative minimum value and practicable to set the superelevation higher than 15mm in RuYiFang station,and it is useful to save the investment and shorten the construction period. and that it offered a new method can be taken for reference by similar projects.
