摘要
在冶勒水电站覆盖层内大跨度隧洞施工时没有先例可借鉴,只有进行相关的技术研究;现在越来越多的大跨度隧道不可避免地设在软岩或土体内,而大跨度覆盖层隧道施工都要面临一些技术难题。为此,就冶勒水电站覆盖层内隧洞施工中的掘进、支护等施工技术进行阐述,以促进覆盖层内大跨度隧洞施工技术的发展。
Without experiences for reference when constructing the large-span tunnel within overburden layers, Yele Hydropower Station has to carry on related technical research. Currently, more and more large-span tunnels are unavoidably built in soft rocks and earth, whereas, all the large-span tunnel construction within overburden layers have to encounter some technical difficulties. This text mainly elaborates construction techniques within overburden layers of Yele Hydropower Station, such as tunnel driving, tunnel support and etc. so as to promote the development of the construction technique of large-span tunnel within overburden layers.
