摘要
渝利铁路经余家隧道穿越齐耀山区,该地区岩溶发育典型,工程地质构造极为复杂。施工过程中极易发生突水、突泥事故,危及施工人员生命安全,造成重大的经济损失;隧道长期排水会造成地下水位下降或疏干,引发地表水干枯或断流,产生不同程度的环境灾害。文章以渝利铁路齐耀山地区岩溶选线为背景,认真分析山区岩溶地区影响铁路线路走向的基本因素,总结了山区岩溶地区铁路工程选线的基本原则,为本线路的选线决策提供了可参考的事实依据。
Chongqing-Lichuan Railway passes through Qiyao Mountain Area via Yujia Tunnel where engineering meets with a complicated geological structure with typically developed karst. Serious accidents from water or mud bursting occur frequently in construction which may endanger workers＇ lives and cause substantial losses in economy. Additionally, an age-long draining of ground water in tunnel might lead to the falling of water level, causing dry-up of flow and bringing environmental disasters. Based on the route selection of Chongqing-Lichuan Railway in Qiyiao Mountain Area, this paper analyzes the basic factors influencing the strike of line in this mountainous karst area, summarizes the basic principles of railway route selection in such area, thereby providing basis for the route selection of this line.
