Research conclusions ： Through making analyses and comparisons of four schemes for route selection of the transriver tunnel and two schemes for construction of the tunnel, the route selection of transriver tunnel should comprehensively considers the track type, passenger flow and the conditions of building stations and laying out track，and it is proposed to adopt the scheme of Yaoludi. For tunnel construction, it is proposed to adopt shield construction with small section of 6.2 m for single track and tunnel, which can effectively reduce the construction difficulties, guarantee the construction security and lower the construction cost.
