Abstract: Sheet pile wall is a potential structure for water-intake project of offshore power station. According to the preliminary design scheme, this paper presents the centrifugal model test on the water-intake project under wave loading. The safety of the structure is analyzed for the different buried depths of sheet pile wall. The centrifugal model test results show that a large horizontal displacement and a large bending moment occur at the cantilever sheet pile under designed wave loading. The main load inducing the displacement and the bending moment is the wave load above the ocean bed surface; and the main bearing capacity is obtained from the lateral earth pressure on passive side of the wall. The increase of the buried length of sheet pile wall cannot reduce the displacement as well as the bending moment of the sheet pile; therefore it cannot increase the bearing capacity of the sheet pile structure effectively.

Key words: centrifugal model, sheet pile wall, displacement, bending moment, bearing capacity
