渝昆高铁与沪昆客专连接线及接轨车站研究

A Research on Chongqing-Kunming High-speed Railway and Shanghai-Kunming High-speed Railway Connection Line and Connection Station

新建渝昆高铁与沪昆客专在昆明南站分场设置。合理确定渝昆高铁与沪昆客专连接线,不仅能减少运输距离,缩短运输时间,同时能缓解昆明枢纽的压力。结合渝昆高铁和沪昆客专线路走向、车站分布及云南省铁路网远期规划,研究了曲靖北-寻甸、曲靖北-田坝、曲靖北-会泽接轨方案,从线路长度、工程投资、地质条件、环境敏感点等方面进行分析,确定曲靖北-田坝为最佳接轨方案。结合田坝站的规模、功能定位及作业量,从工程投资、车站作业能力、行车速度、对G85渝昆高速公路影响等方面进行综合比选,确定田坝站采用2台4线站型方案;从工程投资、运输组织、桥梁布置、相互实施影响等方面进行综合比选,确定正线连通方案为最佳连通方案。

Chongqing-Kunming high-speed railway and Shanghai-Kunming high-speed railway are in scene division in Kunming South Station.Reasonable determination of the connection line between Chongqing-Kunming high-speed railway and Shanghai-Kunming high-speed railway can not only reduce the transportation distance,and shorten the transportation time,but also alleviate the pressure of Kunming terminal.Based on the alignment and station distribution of Chongqing-Kunming high-speed railway,and Shanghai-Kunming high-speed railway and the long-term planning of Yunnan railway network,the connection schemes of Qujingbei-Xundian,Qujingbei-Tianba and Qujingbei-Huize are studied.From the aspects of line length,engineering investment,geological conditions and environmental sensitive points,Qujingbei-Tianba is determined as the best connection scheme.Combined with the scale,function orientation and operation volume of Tianba station,it is determined that Tianba Station adopts two-platform and four-line station type schemes through comprehensive comparison and selection of engineering investment,station operation capacity,driving speed and influence on G85 Yukun Expressway.Through comprehensive comparison and selection of the aspects of engineering investment,transportation organization,bridge layout and mutual implementation influence,the main line connection scheme is determined as the best connection scheme.
