Abstract：
Some tunnel exit of Baohan expressway through state road No.316. Therefore, it is very important to ensure the safety of both new tunnel and existing road. Finite element software Midas was used to simulate construction process of under crossing the tunnel on the basis of CRD method and double sides heading method. The results showed that: the maximum of settlement of road surface is 4.40 mm when CRD method was used, and CRD method can effectively control the settlement and deformation of pavement. Meanwhile, CRD method has fewer construction process, the advantages of short duration.
