文章阐述了从阿德勒(Adler)至Alpika Servis滑雪场间采用矿山法施工的公铁两用隧道特点及其面临的挑战。因施工进度计划紧且最初阶段又无设计资料可利用,该项目开挖方案和开挖设备的比选几乎是和地质勘测同时进行,这就造成诸多重大问题,最终不得不采用综合方法进行开挖。尽管如此,施工队伍还是克服了重重困难,实现了快速开挖作业,避免了施工进度的延误,且大大缩短了其它隧道的开挖时间。
The article describes the characteristics and challenges of the dual-purpose, dual-purpose, dual-purpose tunnel using the mining method between Adler and Alpika Servis ski resorts. Due to the tight construction schedule and the lack of design information available in the initial stage, the comparison of the excavation scheme and excavation equipment of the project is almost at the same time with the geological survey, resulting in many major problems that eventually have to be solved by an integrated approach dig. In spite of this, the construction team overcame various difficulties, achieved rapid excavation operations, avoided delays in construction progress, and greatly shorten the excavation time of other tunnels.
