Abstract

Bohai strait subsea tunnel is an important part of east coastal traffic artery in China. According to the actual factors along the cross sea passage, full deep tunnel scheme is suggested in Bohai strait. The proposal planar line of subsea tunnel starts from Laotieshan cape of Lvshun, ends at Donggang in Penglai, passing through Beihuangcheng island, Daqin island, Tuoji island, Beichangshan island, Nanchangshan island from north to South between the line section. The line is 114km long. One shaft is set up separately for ventilation at Laotieshan cape, Beihuangcheng island, Beichangshan island and Donggang. Landing point in Shandong Peninsula is located at Donggang in Penglai and another landing point in Dalian is located at Laotieshan cape. Railways are used as transportation method and automobiles are transported within the train crossing the sea as a piggy back system. To avoid all kinds of risks, the tunnel is about 80m below the sea floor. The linear of longitudinal section is designed as W shape and the maximum longitudinal slope is set as 18‰, then the tunnel's length is about 125km. Cross section of the tunnel is a combination of double tubes and single tube, serving for the trains and other functions individually. The train speed is designed as 250km/h. The principle of security, reliability, applicability, economy is must be held in designing and construction of Bohai strait tunnel, and the order is not allowed to be changed.
