| 摘 要： | 通过对不同曲率半径下拱杆承受雪载能力的对比分析，得出以下结论对给定矢跨比的双圆弧拱顶，在相同的雪荷载作用下，曲率半径对拱杆承载能力有较大的影响。据此可知，在不改变拱杆截面参数的前提下，通过调整拱顶曲率半径，可提高拱杆的承载能力，为进一步优化连栋塑料温室结构设计和降低生产成本提供科学研究。

| Abstract: | Through the contrastive analysis of the arch carrying snow loading capacity under the different radius of curvature, some conclusions are summed up: radius of curvature has much influence upon the carrying capacity for the ratio of high-span to double vault under the same snow loading. For reasons given above, we can improve carrying capacity through adjusting the radius of curvature without changing section parameter, it will offer science reference to optimize structure design of multi-span plastic greenhouse and to reduce the operating costs. |

| Keywords: | double vault radius of curvature carrying capacity |
