摘　　要：针对正常水深、临界水深、收缩水深和共轭水深这四种明渠特征水深,通过对梯形明渠水力计算公式进行适当变换,建立水力计算的数学模型,借用MATLAB GUI系统的可视化操作界面进行编程设计,实现快速、准确、方便地计算且结果精确可靠,可供工程实际参考应用.For normal water depth,critical water depth,contracted water depth and conjugate water depth oncharacteristic depths of open channel,through the trapezoidal open channel hydraulic calculation formula transformingeach other,a mathematical model of hydraulic calculation is established. By means of MATLAB GUI system visualinterface,the programming design is given to realize fast,accurate and easy calculation. The results which areaccurate and reliable can be used as a reference for actual projects.
