叙大铁路规避不良地质选线设计

Route Selection of Xuyong-Gulin Railway Avoiding Poor Geologic Zones

叙大铁路位于四川省泸州市境内,是一条以煤炭运输为主;兼顾沿线客货运输的地区性支线铁路。针对本线主要服务于古叙矿区的特点,在铁路选线设计中,以地质选线为前提,力求靠近大采矿区,规避煤矿采空区、岩溶漏斗、暗河等不良地质,科学经济安全的确定线路走向,合理选择坡度折减系数及最小曲线半径,降低工程风险,节约工程投资。

The Xuyong-Gulin railway is located in Luzhou, Sichuan province. It is a regional feed-in railway for coal transportation and for passenger and freight delivery as well. The main purpose of this railway line is to serve the Guxu Coal Mine Areas. The priorities are given to the geological situations to enable that the railway line is close to the main coal mine areas, that the unfavorable factors such as poor geologic zones , coal gab area, karst funnel and subsurface stream are avoided in the route planning, so that the project and investment risks are reduced by way of scientific, economic and safe measures to make sure that appropriate slope reduction factors and minimum radius of curves are achieved.
