复杂地质条件下铁路隧道施工技术

随着我国高速铁路飞速发展,高达350km/h的运营速度对铁路隧道施工技术提出了更高的要求。高速铁路工程常常需对隧道进行修建来实现山岭地带的穿越,故而隧道属于铁路工程中必不可少的一部分。为确保铁路隧道工程的质量和安全性,必须注重相关施工技术的有效运用,攻克复杂地质施工难关,对施工过程中可能发生的各种问题进行有效消除,从而切实保证施工的安全,确保工程施工的有序开展。基于此,文章主要从岩溶地质条件、浅埋偏压地质条件、膨胀性地质条件、软弱围岩地质条件等方面探讨复杂地质条件下的铁路隧道施工技术,希望通过此次研究能够对铁路隧道施工技术提升产生帮助。

With the rapid development of high-speed railway in China,the operation speed of up to 350 km/h has posed higher requirements for railway tunnel construction technology.High-speed railway project teams often need to build a tunnel to achieve the crossing of the mountain area,so the tunnel is an indispensable part of the railway project.In order to guarantee the quality and safety of railway tunnel engineering,we must focus on the effective use of relevant construction techniques,overcome the complex geological difficulties of construction,and effectively eliminate all kinds of problems that may occur in the process of construction,so as to ensure the safety of construction and the orderly development of engineering construction.Based on this,this paper mainly discusses the railway tunnel construction technology under complex geological conditions from the aspects of karst geological conditions,shallow buried bias geological conditions,expansive geological conditions,weak surrounding rock geological conditions and so on.It is hoped that this study can be helpful to the improvement of railway tunnel construction technology.
