摘要：	To determine the drag coefficients of geocontainers dumped from an angle-adjustable bevel installed on the side of a ship, an investigation was conducted. First, the settling equation and formulas for the geocontainer were deduced. Second, a screening experiment was conducted to determine the optimal factor groups with proper settling regularity from a combination of factors, that is, the dimension and filling ratio of the geocontainer, the bevel angle, and the sliding distance. Third, trajectories of the geocontainers were obtained from a regularity experiment under flow conditions with different water depths and flow velocities based on the optimal factor groups. According to the regularity experiment, geocontainers are more likely to rotate in conditions of deep water and high flow velocity, which cause an increase in the horizontal settling distance error. Fourth, a computational model to determine the drag coefficients of the geocontainers was proposed according to results of the experiment. Last, drag coefficients of the optimal factor groups were calculated according to the proposed computational model (CDx = 0.3–4.27; CDz = 0.84–2.53).
