摘要
断面收缩水深是水力计算中所需的重要参数之一,采用MATLAB语言编程,通过具体实例,给出梯形、无压流圆形、平方抛物线形、立方抛物线形4种常见断面形式下求解收缩水深的方法。因为它们都是直接采用理论公式进行计算,故较之传统的计算方法包括试算法、图解法等计算过程简单、精度较高、方法易掌握。
The cross-section contraction water depth is one of the most important parameters in hydraulic calculation.This study provides a calculation method of contraction water depth for four common cross-section types including circular section without pressure,square parabolic-shaped section,cubic parabolic-shaped section and city-doorway-shaped section through the concrete case based on MATLAB language.Compared with the traditional calculation methods including test calculation and graphic method,it is simple in the calculation process,high in the precision,and easy to master because it is calculated by adopting directly the theoretical formula.
