Due to the lack of engineering examples and research on steel pipe piles in marine dense gravelly soil bearing stratum，relying on a port project in Peru，we study the pile driving and bearing characteristics of steel pipe piles in gravelly soil bearing stratum.We carry out the model test in advance in China to obtain the parameters of simulated pile sinking，and conduct the drivability analysis of pile sinking to improve the construction plan work.Then，we carry out the pile sinking test，high strain test and static load tests on the site，and test the side resistance and end resistance at the same time.The results show that the bearing capacity，unit area side resistance and end resistance of open steel pipe pile increase with the increase of soil penetration after entering the dense gravel soil bearing layer，but the increase range gradually decreases.After entering the bearing layer for 1 m，the penetration of the pile will be difficult，and then the unit area end resistance will gradually stabilize.Limit unit area end resistance of gravelly soil is not less than 10.5 MPa.The end resistance of the steel pipe pile is mainly provided by the pile end resistance，the reaction force provided by the soil plug bearing capacity is small，the pile soil plug coefficient is relatively low.
