Abstract Research purposes: In the design of the supporting structures for the mountain tunnel with high water pressure, how to determine the water pressure value on lining is the key element of the design. For the Liantang Tunnel on the eastern highway in Shenzhen, the distribution of seepage field of Liantang tunnel is studied in theory. The Liantang Tunnel is located in the hilly area of southwest Shenzhen where is the influence area of the Shenzhen fault with developments of fault and joint fissure to break out the surrounding rock. As the tunnel is close to the Shenzhen Reservoir and is under the constant water level, the tunnel will be always affected by the high water pressure in the future if the under-passing scheme is adopted to the tunne.l Therefore, the study on the distribution of seepage fields of the Liantang Tunnel and surrounding rock has the instructive significance to both the structure design and drainage design.
Research conclusions: The verifying calculation is carried out separately to seepage field of the tunnel with finite differential geotechnical software package FLAC3D and Harr solution. By calculation comparison, the contour maps of the seepage field distribution made with the analytical solution, the definite differential geotechnical solution and Harr solution are gained respectively. By comparison, the correctness of the analytical solution to the seepage field distribution of deep buried tunnel is proved.
