随着铁路客运专线的大规模发展，将会不断遇到软弱围岩大断面隧道的施工问题，针对目前我国客运专线隧道大断面软弱围岩施工的现状，分析了施工中存在的主要技术问题，并提出了相应的对策,以期对目前在建和拟建的隧道工程提供参考和借鉴。

With the development of Passenger Dedicated Railway (PDR), problems in the construction of tunnels with large crosssection in soft rock mass will be increasingly encountered. Attention should be paid to several aspects of tunnel construction, such as advance geology prediction, rapid mechanized construction, stability and deformation control in tunnel face and in rock mass, construction ventilation, waterproofing and drainage and application of durable concrete. They are put forward and interpreted, in accordance with the difficulties encountered in the construction and the problems existing in the early construction stage, which may provide some references for relative tunnel projects under construction and/or future tunnel projects.
