【Abstract】 Based on the flow characters of skew bridge crossing and the theory of wake spread as well as decay, the iterative calculating formulas of backwater and relation of bridge aperture design are deduced. In order to verify them, the value of backwater of a skew bridge crossing is calculated. The results agree with the experimental ones.更多还原
