Comparative Study on Seismic Design Method of High-Piled Wharf of Different Depth in China and Japan

As many high-piled wharves are in an earthquake zone in home and abroad, so it is vitally important to conduct seismic design to ensure them with a certain seismic capacity. Studies showed that the wharves with straight piles have better seismic performance than wharves with oblique pile. According to the standards in China and Japan, this paper will compare the indicators of seismic performance, including the calculation length of piles, seismic inertial force, bearing capacity etc. The difference between Chinese code and Japanese code will be confirmed through comparison. The comparative results show that the differences mainly in the embedded solid position and the horizontal force etc. Additionally, according to the comparison of different depth of high-piled wharf, there is an increasing trend of the indicators with increasing depth of water.
