Due to the complex geological condition，it has a great difficulty to select the structure for the 2×50，000 DWT wharf in Luoyuan bay. To tackle this problem，research and comparative analysis of the wharf structure under similar geological conditions are carried out，and the structure scheme of the wharf is optimized. From the perspectives of technical feasibility and economic rationality，the optimal high piled wharf with the top opened frontal steel sheet pile structure is analyzed.At the same time，the measured data of the on-site survey and operation parameters of the completed wharf are collected and compared with the calculated results，thus verifying the reliability and economic rationality of the structure of the pile high piled wharf with top opened frontal steel sheet piles.
