武广客运专线韶关至花都段总体设计

Overall Design of Shaoguan-Huadu Railway of Wuhan-Guangzhou Passenger Dedicated Line

研究目的:武广客运专线是我国2020年前铁路中长期发展规划中北京-武汉-广州-深圳客运专线中的一段,与既有京广铁路构成京广铁路大通道,是我国铁路网的重要繁忙干线铁路。本文主要介绍了韶关至花都段部分复杂地段、特殊地段选线、新技术采用和总体设计中的一些体会。研究结论:本段线路比选了樟市方案、清远站位方案。其中樟市东、中、西3个方案,经从地形地貌、地质条件,环境影响,技术经济等方面进行了比较,推荐樟市东方案;清远站位白家塱站址及洲心镇站址2个方案,经从专业技术和经济两方面比较,推荐白家塱站址方案。同时,该段线路在专业设计时,在轨道、路基、隧道等方面采用了新技术,为铁路客运专线建设积累了宝贵的经验。

Research purposes ： Wuhan - Guangzhou Passneger Dedicated Line is an important part of Beijing - Wuhan - Guangzhou - Shenzhen Passenger Dedicated Line planned in Medium - Term and Long - term Railway Plan and will be a busy railway, composing of the railway corridor from Beijing to Guangzhou with the existing Beijing - Guangzhou Railway Line. The introduction is given in this paper to the overall design of Shaoguan - Huadu Railway of Wuhan - Guangzhou Passenger Dedicated Line, including the routes selections in complicated geological area and special area and application of new technologies. Research conclusions：After the comparison of Zhangshi Plan with Qingyuan Plan in the fields of landform, geological condition, environment protection, technology and investment, the Zhangshi Plan is recommended. In this plan, the railway station is recommended to locate in Baijialong through comparison of that in Zhouxinzhen in the fields of the technology and investment. In the meantime, the new technologies are adopted for construction of track, subgrade and tunnel to accumulate the experience for construction of passenger dedicated line.
