岸边式溢洪道泄槽安全超高与边墙高度的确定

Deciding Safe Superelevation and Peripheral Wall Height of Discharge Trough in Banked-spillway

以实验为基础 ,提出了定常工况的边墙安全超高按水深分段计算的修正公式 ,并通过数值计算 ,给出了确定非定常工况边墙高度的方法和计算公式 ,结果表明这种确定的安全超高和边墙高度 ,既保证了一定的安全裕量 ,也不致于造成浪费 ,基本符合工程实际情况 。

Based on the sectional calculation of peripheral wall safe superelevation according the different depth under constant condition and using numerical calculation,the method and formula for height to decision under unconstraint condition are afforded.The resulting values of superelecation and wall height can offer safety margin and avoid wasting.Furthermore,they conform to the practice well and can be used as a reference to design spillway.
