Because of the heavy weight of the gravity wharf，the foundation of undisturbed soil cannot meet the requirement of bearing capacity. In order to solve the problems such as the shortage of stone materials and the insufficient bearing capacity of the foundation for the construction of inland river wharves，and improve the utilization rate of the excavated earth resources，we combine with the design experience of the Yuejin Ditch and the Liangshan County wharf in Jining area of Shandong Province，compare and analyze the characteristics and applicability of different wharf structural schemes according to the construction features，hydrogeological conditions and operational requirements，adopt a new type of small wooden pile composite foundation scheme in the structural design for inland river wharf，and propose the new ideas for optimization and innovation from the aspects of the selection of excavation earthwork for backfill materials behind walls，the structural cross-section of wharves，the track foundation type of ship loaders，etc. to apply for project construction. At the same time，we summarize the principle and calculation method of small wooden pile composite foundation，selection of backfill parameters，construction quality control etc. The results show that adopting the gravity structure of cast-in-place concrete and the composite foundation of small wooden piles as the main structure form and foundation treatment method of the wharf，and adopting the dredging earthwork as the backfill material behind the wall can ensure the quality of the project and save the investment.
