摘　　要：高寒地区深埋长隧洞地质条件复杂,高寒缺氧、断层构造和软岩变形是影响工程施工的突出性问题,钻爆法施工和TBM法施工各有优缺点,且均存在一定的难度。为此,对高寒地区深埋长隧洞施工方案需要进行综合比选,选择时应紧密结合隧洞勘探揭露的工程地质条件和拟定的工程线路方案,避免采用存在工程风险相对较大的施工方案。通过确定合理的施工方案,实现工程投资、施工工期及施工安全风险最佳效益组合。For the long deep-buried tunnel in alpine region,the outstanding issues such as complicated geological conditions,alpine-cold and hypoxia,fault structure and soft rock deformation influence the engineering construction.In consideration of the pros and cons of drilling and blasting method and TBM method,the comparison and selection of construction schemes of long deep-buried tunnel in alpine region are conducted,though both have difficulties in construction practice.It is necessary to combine the engineering geological condition exposed in the survey with the planned route and scheme so as to abandon the scheme that has relative larger risk.On this basis,the reasonable construction scheme is determined and the optimal profit combination of engineering investment,construction period and risk can be realized.
