摘要
Lagos红线轻轨项目是一个城市轨道交通与国铁共线运营的项目,在国铁城区段正线两侧设站台,停靠轻轨旅客列车。由于轻轨与国铁非同一业主,国铁项目业主同意国铁与轻轨共线运营,但不同意轻轨项目站台施工期间对国铁正常运营造成影响。传统的站台设计思路在该项目不适用,需要改变设计思路进行特殊形式站台研究;通过研究站台施工对国铁运营的影响分析,提出了悬壁式站台设计思路,对站台进行设计研究。通过将站台与雨棚整体设计,站台面悬空,使得站台基础避开了运营国铁的路基,避免了站台施工对国铁的运营影响,推动了项目的顺利进行,并节省了工程投资。在今后既有线改造加站台时,悬壁式站台设计思路既能减少对既有线运营的影响,还能节省工程造价。
The Lagos Red Line Light Rail Project is a co-operation project of the urban light rail and the National Railway.Platforms are set up on both sides of the main line of the urban section of the National Railway to stop light rail passenger trains.Since the light rail and the national railway are not owned by the same owner,the national railway project owners agree that the national railway and the light rail will operate on the same line,but they do not agree that the construction of the light rail project will affect the normal operation of the national railway.The traditional platform design idea is not suitable for this project,and it is necessary to change the design idea to conduct a special form of platform research.Through the analysis of the impact of platform construction on the operation of the national railway,the design idea of the suspended platform is proposed,and the platform is designed and studied.Through the overall design of the platform and the canopy,the platform surface is suspended,so that the platform foundation avoids the subgrade of the operating national railway,avoids the impact of the platform construction on the operation of the national railway,promotes the smooth progress of the project,and saves engineering investment.In the future renovation of the existing line of the platform,the design idea of the suspended platform can not only reduce the impact on the existing line,but also save the engineering cost.
