摘要: 基于斜交桥渡的水流特点及尾流扩散理论,推导了桥前计算塑水的迭代公式以及相应孔径设计的表达关系,经计算,壅水的计算值与某山区斜交桥渡的试验资料吻合很好.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.
