【摘要】：随着我国"一带一路"倡议的推进,跨国运输通道的建设成为倡议实施的关键环节之一,而我国建设复杂地质条件下跨国基础设施的经验尚不丰富。"中—尼—印铁路通道"是一条途经尼泊尔,连接中国和印度2个大国的运输通道,基于实地考察,分析该通道建设的必要性及建成后的效益,对线路进行初步规划,并总结该通道建设的难点:铁路轨道坡度大;沿线区域地质构造复杂;周边基础设施落后,施工条件恶劣;大量深长隧道以及大跨径高桥梁;环境以及气候条件复杂。同时对沿线隧道以及桥梁的建设可行性进行分析,并给出施工建议:沿线隧道采用以TBM法为主、钻爆法为辅的施工方法;桥梁建设则因地制宜,根据不同区间的地质特点,采用相应的建设方法。
[Abstract]:With the development of "Belt and Road" in China, the construction of transnational transportation channels has become one of the key links in the implementation of the initiative, but the experience of building transnational infrastructure under complex geological conditions is not yet rich in China. " China-Nepal-India Railway Corridor is a transport passage through Nepal linking China and India. Based on field investigations, the necessity of the construction of the channel and its benefits after completion are analyzed, and the preliminary route planning is carried out. The paper also summarizes the difficulties in the construction of the tunnel: the railway track slope is large; the regional geological structure along the line is complex; the surrounding infrastructure is backward and the construction conditions are poor; a large number of deep tunnels and long-span high bridges; the environment and climate conditions are complex. At the same time, the feasibility of the construction of tunnels and bridges along the route is analyzed, and the construction suggestions are given as follows: the construction method of tunnel along the route is based on TBM method, supplemented by drilling and blasting method, and the bridge construction is adapted to local conditions, according to the geological characteristics of different sections, Adopt the corresponding construction method.
