The steel tubular-sheet pile wharf is widely used in deep-water wharves abroad due to its construction convenience, adaptability to complex geology, and cost-effectiveness. However, understanding the complex interaction between steel pipe piles, steel sheet piles, and soil in this structure is still in the research stage. China lacks sufficient knowledge about the force characteristics of this structure, particularly in terms of earth pressure theory. Therefore, it is essential to conduct research to improve the calculation of earth pressure in this structure. Based on on-site monitoring data from a 100,000-ton steel tubular-sheet pile wharf, it was observed that the soil pressure on the front wall increases nonlinearly with depth but decreases beyond a certain excavation depth range. This study compares and analyzes results from theoretical formula calculations, numerical simulations, and on-site monitoring data of soil pressure, proposing correction parameters for earth pressure calculation. Based on this analysis, correction parameters for earth pressure calculation within the excavation depth range are proposed. Parameters for soil pressure calculation above the excavation depth range are adjusted, considering a cement mixing pile cohesion of 60 kPa and an internal friction angle of 18°, which better aligns with the actual conditions of this structure.
