摘要:
许协庆曾研究具有平行边墙的,头部由圆弧组成的二元半无限闸墩的绕流问题。但该文数学方法似不够严格。
本文用不同的数学方法研究这一流动问题。应用本文提供的方法和公式,无论闸墩头部夹角为任何值,均可以理论上精确计算闸墩头部的流速。本文还对文中计算的4个角度重新进行了计算,以估计文[1]计算的误差。

Abstract:
Potential flow around semi-infinite gate piers bounded from two parallels and head part formed by two circular arcs has been analysed by Hsu Hsieqing.But its methematical method was nonrigorous and lacked of theoretical proof on validity of computation, so it needs to be checked by teat.
In this paper we discuss the same problem of flow by using another mathematical method.With the method and formulas in this paper, it is possible to calculate theoretical Telocity of arbitrary angle of head part of gate piers with great precision but little effort.The coefficients and parameters under four angles of head part were calculated in the preceding paper are recalculated in this paper and the solutions are accurate.
