Ship sailing resistance is an important index of cross section size optimization of restricted channel. Through real ship experiment with one typical ship in inland restricted III channel, the relationship between ship sailing resistance and factors such as water depth to draft ratio, discharge section area and so on is studied. And modified calculation formula of ship sailing resistance is put forward. The results show that as water depth to draft ratio decreases, or discharge section area becomes smaller, ship sailing resistance will increase significantly. By introducing two parameters: section blockage ratio and water depth to draft ratio, the Эиванков formula of ship sailing resistance calculation is modified, and the calculation accuracy which the modified formula applied in restricted channel has greatly improved.
