Majishan unloading port in Baogang locates in the open seas where the engineering region is deepwater with exposed batholiths as the geological conditions. The designed pile foundation is rock-socketed pile with the artificial foundation bed filled with packed sand and macadam, with the expectation of fulfilling the requirement of stability of rock-socketed steel pipe piles during the construction period. To obtain the stability conditions of the single bent rock-socketed steel pipe piles, a physical model test is carried out under the influence of waves and currents. As can be obtained from the test, the main influencing factors are the depth of rock-socketed pile and the length of artificial foundation bed. The number of piles should be 4 on condition that the depth of rock-socketed pile is 45 centimeters high and the length of artificial foundation bed is 7 meters long with the identical water level and wave height.
