深圳至深汕合作区铁路建设方案研究

Research on the Construction Scheme of Shenzhen to Shenshan Cooperation Zone Railway

深圳至深汕合作区铁路大部分位于深圳市主城区,控制因素较多且西丽站已有多条高铁引入,通道选择较为困难。为此,对深圳枢纽西丽站接轨方案、龙山公墓段方案、坪山至深汕合作区线路走向方案等进行多方面比选。经研究,深圳枢纽西丽站接轨推荐车站东咽喉北侧引入方案,优点为可减少通道用地、征拆少、投资省;龙山公墓段推荐采用隧道方案,优点为能减少片区成建制房屋的拆迁,避免对储备地块及龙山公墓造成切割,工程实施对既有厦深铁路影响较小;坪山至深汕合作区段推荐沿厦深铁路方案,优点为线路短1.2 km,投资省5.8亿元,沿线吸引客流能力较强,与城市规划和沿线地方政府意见相符。研究表明,新建线路区间选线和接入枢纽是一个比较复杂的体系,应结合项目功能定位、沿线城市控制点分布情况及地区铁路枢纽总图规划等进行详细研究。

The channel selection of the Shenzhen-Shenshan Cooperation Zone Railway is difficult to be determined since the railway located in Shenzhen’s main urban region which has numerous control variables,and the Xili Station is a hub which has many railway lines connected.Therefore,the Shenzhen-Xili Station connection plan,the Longshan cemetery section plan,and the Pingshan to Shenzhen-Shenshan route plan were all chosen and conducted a variety of comparisons.The plan of connecting the north side of the east throat of the station was recommended for the Shenzhen-Xili Station connection.The advantage of the scheme included its low passage land,less land demolition requirements,and low cost.The underground plan was recommended for the Longshan cemetery section because it could reduce destruction of existing building in the area and avoid cutting the reserve land and Longshan cemetery.It had little influence on the Xiamen-Shenzhen Railway.The plan along the Xiamen-Shenzhen railway was recommended for the Pingshan to Shenzhen-Shenshan route.It had advantages including that the line was only 1.2 km,and the investment could be reduced by 580 million yuan.The ability to attract passengers was strong,which was consistent with urban planning and local government opinions.According to research,the route selection and access hubs of newly constructed lines were relatively complex system,and detailed research should be conducted based on the project’s function positioning,the distribution of control points of cities along the line,and the general map planning of regional railway hubs.
