U形长薄壳渡槽的横向分析公式有等厚壳槽公式、简化公式和底部加厚公式等.随着水利建设事业的发展,大断面渡槽逐渐增多,为了经济并便于施工 起见,设计多采用轻型结构,薄壳渡槽的形式则趋向采用U形、半椭圆形、抛物线形等混凝土薄壳结构.在同种形式中还有不同加厚情况,如U形渡槽就有:底部局部 The transverse analysis formula of U-shaped long thin-shell aqueduct includes equal-thick shell-slot formula, simplified formula and bottom thickening formula. With the development of water conservancy construction, large-section aqueducts gradually increase. For the sake of economy and ease of construction, the design is often used. In light structures, thin shell aqueducts tend to use U-shaped, semi-oval, parabolic, etc. concrete shell structures. There are different thickening conditions in the same form, such as U-shaped aqueducts are: bottom part
