| Abstract: | Tengzhou City Fenghuang Tunnel and Approach Project is located in Gaotie New Area of Tengzhou City. Its total length is 2.6 km with six lanes in both directions, in which the jacking-in part of the tunnel is 48 km long. In order better to complete the design of tunnel jacking in, the jacking-in part is specially introduced including the comparison of spanning scheme, the comparison of supporting scheme, the design overview of pipe curtain and the calculation of pipe curtain deflection. A certain level of reference can be provided for the similar jacking-in construction projects with the pipe-curtain support method. |
