摘要
本文从我国各主要水系的大量实测资料分析入手,采用数理统计法,建立了水流通过段在造床流量下的水文水力学特征值与河床几何形态之间的数值关系,并提出各类河段桥孔长度的计算公式,用算例介绍了该公式的应用。
In this paper, quantities of field observation data of the rivers in China are analyzed by the method of mathematical statistics, and formulae for the bridge opening length computation of various types of river reaches are suggested. The formulae presented are established according to the relationships between the hydraulic features in the condition of river bed formation flow and the geometrical shapes of rive/ bed. Finelly, practical examples are given.
