Abstract：Research purposes: Through discussion on the construction scheme of Liulin Tunnel entrance in crowed population area, this paper summarizes the construction experiences of the tunnel entrance, including the construction scheme, construction method, construction measures and caution for attention in construction of the tunnelentrance, for the purpose of providing the reference to the similar works.
Research conclusions:Liulin Tunnel is located in the crowded population area. Successful construction of its entrance shows the construction scheme, construction method and constructionmeasured for the tunnelare economic and feasible.The method and scheme ofadopting short footage, loose blas,t static blas t, small pilot tunnel along with using anchor to spurt the ne t, the steel pipe column to hang the Bruckernetand to laymortar to the slice stone overcome the problems in construction of the tunnel entrance in the steep slope and crowed population area and the problems of synchronic operation for the tunnel connectedwith bridge, andmeet the requirements under special construction condition.
