在水利工程建设中, 梁式U型薄壳渡槽被大量采用,许多专业人员对其计算理论进行了深入的研究。其横向内力计算,有等厚断面计算公式、用化引等代截面法计算变厚断面的公式、用变换截面原理适用多种类型断面的计算法及折板法等;在槽身应力分析中,有常用的材料力学法、近期出现的有限单元法、空间法和壳体理论计算
In the construction of water conservancy projects, beam-type U-shaped thin-walled aqueduct has been widely used, and many professionals have conducted in-depth research on its computational theory. The calculation of transverse internal forces has the formula of equal thickness section, the formula of thickening section by the method of indexing and so on, the calculation method of various types of sections by the principle of transformation section and the folding plate method, etc. In the stress analysis of the tank body , There are commonly used method of material mechanics, the recent emergence of finite element method, space method and shell theory calculation
