杭衢铁路新安江至金千货场段线路方案优化

杭衢铁路位于浙江省西部建德市和衢州市境内,是长三角城际路网的重要组成部分,是沪昆铁路杭衢段的辅助通路。本文从保护自然景观、节省工程投资的角度考虑,对杭衢铁路新安江特大桥线路纵断面方案进行了优化;在与行车速度相匹配的前提下,结合满足轨温调节器设置的平面条件、绕避居民回迁区以避免二次拆迁等因素,对杭衢铁路新安江至金千货场段线路平面方案进行了优化。本文线路优化的研究思路可供类似工程参考借鉴。

Optimization of Route Scheme of Hangzhou-Quzhou Railway from Xin an River to Jinhua-Qiandaohunan Railway Freight Yard

Hangzhou-Quzhou Railway,located in Jiande City and Quzhou City in the west of Zhejiang Province,is an important part of the Yangtze River Delta intercity railway network and an auxiliary passage of Hangzhou-Quzhou Section of Shanghai-Kunming Railway.The paper firstly optimizes the profile design of the section of Xin an River Super Major Bridge of Hangzhou-Quzhou Railway from the perspective of protecting the natural landscape and saving engineering investment,and then optimizes the layout of the section of Hangzhou-Quzhou Railway from the Xin an River to the Jinhua-Qiandaohunan Railway Freight Yard on the premise of matching with the running speed,combining with the plane conditions of rail temperature regulator,and avoiding the residents relocation area to avoid the second demolition.The research ideas of route optimization in this paper can be used for reference by similar projects.
