| 摘 要： | 普通Ｕ形薄壳渡槽底部槽身内壁拉应力过大，渡槽的抗裂防渗难于满足。而且一般需要设横向拉杆，给特大型渡槽设计带来不便。为此，提出一种不设横向联系杆的半椭圆形薄壳渡槽结构，其槽身拉应力可人为调节，可供有关工程设计参考。

| Abstract: | There are too big tensile stresses in the bottom of a general thin shell aqueduct with U-shape cross section, for this aqueduct the require of seepage proof is hardly satisfied and some draw bars must be set up along the crosswise of aqueduct. It is not convenient in the design calculation of big aqueduct. Proceed from engineering application, this paper puts forward a semiellipse thin-shell aqueduct with out draw bar where the tensile stresses can be adjusted. |
