川南城际铁路自贡东站平面布置方案研究

川南城际铁路自贡东站为内自泸城际铁路与自宜城际铁路的接轨站,远期预留成自高速铁路引入条件,车站布置对整条线路能力和工程投资都有较大影响。在阐述自贡地区铁路概况的基础上,分析自贡东站主要作业内容、车站作业量和车站正线贯通方向,提出共站分场布置方案、站内同向正线拉开间距设岛式中间站台布置方案,以及车站正线四线并行引入布置方案,并从运输组织、施工干扰和工程投资等方面对布置方案的优缺点进行分析比较,推荐采用站内同向正线拉开间距设岛式中间站台布置方案。

A Study on the Layout Scheme of Zigong East Station in Southern Sichuan Intercity Railway

Zigong East Station of Southern Sichuan Intercity Railway is the junction of NeijiangZigong-Luzhou Line and Zigong-Yibin Line, which reserves Chengdu-Zigong railway introduction conditions in the future. And the layout design of the station has a great impact on the line capacity and engineering investment. On the basis of describing the general situation of Zigong hub, this paper analyzes the main operation content, station operation quantity, station connection direction and route layout of Zigong East station, and puts forward three layout schemes which are two station yards arranged in parallel, positive line on the same direction pull apart and set the intermediate platform, and four positive line parallel introduction to the station. we analyze and compare the advantages and disadvantages of the layout schemes from aspects of transportation organization, construction interference and engineering investment etc., and recommend the scheme of positive line on the same direction pull apart and set the intermediate platform.
