近距大跨超浅埋双洞分修隧道穿越铁路施工技术

Ultra Shallow Double Hole Tunnel is Divided Through Construction Technology of Large-Span Railway Close

国家经济水平不断提升的同时,也推动了我国各项基础建设的发展,铁路建设规模也随之持续扩大,铁路建设技术水平也快速提升。通常铁路建设施工中,其地理因素对整个施工有着很大影响,施工中要注意通风、防排水及施工机械配套技术等问题。文章分析近距大跨超浅埋双洞分修隧道穿越施工特点和近距大跨超浅埋双洞分修隧道穿越施工方案,为我国铁路工程建设提供可靠的理论性依据。

The country＇s economic level is rising at the same railway construction scale also will continue to expand, railway time, but also to promote the development of China＇s infrastructure, construction technology level is also rising rapidly. Usually the construction of railway construction, the geographical factors have a great impact on the entire construction, construction should pay attention to ventilation, drainage and construction machinery supporting technology and other issues. This paper analyzes the construction characteristics of the close-span large-span ultra-shallow-buried double-tunnel subway tunneling construction and the short-distance and large-span ultra-shallow-buried tunnel construction scheme.
