【摘要】：结合高速铁路兰州至张掖三四线乌鞘岭越岭地形地貌、不良地质、自然保护区等控制因素及相邻既有铁路情况,按照高速铁路"短、直、快"的选线原则之外,从工程地质、环保、经济、安全、工期等方面对地质条件复杂的乌鞘岭越岭方案进行研究,经多方案分析研究,沿既有铁路越岭隧道并行敷设,不但可满足高速铁路选线原则,还可以充分利用既有隧道斜井、竣工地质勘察资料及施工措施经验,解决乌鞘岭工程地质复杂选线问题。
[Abstract]:The combination of high-speed railway from Lanzhou to Zhangye three or four line of Wushaoling mountain topography, geological factors, control of nature reserve and adjacent to existing railway, high-speed railway in accordance with the "short, straight, out of line selection fast" principle, from the engineering geology, environmental protection, economy, security, and other aspects of research on Ukraine period Wushaoling mountain line scheme in complex geological conditions, analysis of the project, along the existing railway tunnels are laid in parallel, can not only meet the requirements of high-speed railway line selection principle, can make full use of the existing tunnel construction, the completion of geological survey data and experience of construction measures, solve the Wushaoling complex engineering geological line selection problem.
