文摘In this paper, the transportation mode of tube during the immersed tunnel engineering in Yangtze River incorporated, mathematical models of the combination of the tube and four barges are established when it is towed by a tugboat through an elastic rope and pushed by two pushers. Based on evaluating the hydrodynamic derivatives by regressive formula, the simulations and analysis of the whole maneuvering motion course are accomplished. They include sway and yaw motion simulation of the combination and prediction of maneuvering motion such as turning circles of different rudder angle under the condition of being pushed by two pushers. The coincidence of the prediction with the results of model test is good.
