摘　　要：通过对不同传力方式拱杆承受雪载能力的对比分析 ,得出以下结论 :在相同的雪荷载作用下 ,不同的传力方式对拱杆承载能力有较大的影响 .在温室结构设计中 ,要按照等强度原则 ,重视结构方案的整体性与局部性的统一 .计算结果表明 :华东型连栋塑料温室结构设计合理 。Through the comparison analysis on the capacity of the arch's carrying snow under different ways of force transformation, some conclusions are summed up. Different ways of force transformation have different influences upon the capacity under the same snow load. Much attention should be paid to the coherence between structure scheme and the whole in structure design for greenhouse according to the principle of equal strength. The calculated results indicate that the structure style of East China multi-span plastic greenhouse is reasonable, and has excellent mechanical properties.
