【摘要】 针对超大型渡槽设计中的特殊问题 ,提出半椭圆型薄壳渡槽并分析其过水断面计算方法 ,使用MATLAB语言开发出半椭圆型渡槽水力计算图算法关系曲线与U型渡槽水力计算软件AWC ,验算渡槽的输水能力或决定渡槽的底坡 ,确定渡槽的截面尺寸。可供类似渡槽、明渠设计参考。更多还原

【Abstract】 According to the specific characteristics of the big aqueduct a thin-shall aqueduct with semiellipse cross section has been put forward and the calculation method of this cross section has been analyzed. A set of curves used in graphic method are drawn and a program AWC used in design calculation is written in MATLAB language,for checking the water transfusion capacity, or calculating the bottom slope, or determining the section dimensions of an aqueduct. Both can be applied to design of similar aqueducts.更多还原
