Abstract: Through real-ship tests, key observations were conducted on the characteristic segments such as the straight section in Yangtze-to-Huaihe communication segment, the continuously curved section in the lake area and bridge clustering area in the Yangtze-to-Huaihe water diversion project. The change characteristics of the rudder angle, the pitching and rolling and the amount of subsidence and their influencing factors under the conditions of different characteristic segments were analyzed. The research results show that under the condition of artificial canal waterways, the distribution of rudder angles is relatively concentrated, and the range is smaller. The pitching angle is not affected by the direction of the waterway or bridges and culverts, and the longitudinal attitude is relatively stable. The rolling angle is significantly influenced by the turning radius of the bends, and the range of rolling angles of the continuously curved section in the lake area is the maximum (0.78°). The subsidence is relatively small in the experimental sections with different waterway characteristics, with a maximum subsidence of 0.193m, which accounts for only 6.03% of the draft depth.
