| 摘 要： | 利用有限元法详细计算了不同H/B下无拉杆和不同拉杆间距简支梁式矩形渡槽槽身的应力,根据计算应力,以最大主应力作为控制标准,分析了H/B以及拉杆间距对槽身横截面应力的影响,提出了渡槽槽身应力与拉杆间距之间的关系.

| Abstract: | The stresses of rectangular aqueducts with simply supported beams in the absence of bridle rods and with bridle rods of different distances were calculated under different values of H/B by the finite element method. Based on the stresses calculated, the maximal principal stress was taken as the control criterion of the effects of H/B and the distance between bridle rods on the stress of cross section of aqueducts, and the relationship between the aqueduct stress and the rod distance was derived. The result is of certain reference value to practical projects. |
