摘　　要：从桥型方案构思、拟定结构尺寸、结构计算等方面对一座不等跨连拱拱桥作介绍和分析。采用m法考虑桩土共同作用,计算群桩基础抗推刚度,用以模拟弹性约束边界条件。利用有限元软件建立三维模型,对结构承载能力及稳定性进行计算分析。This article introduces and analyzes the bridge scheme conception, proposed structure dimension and structure calculation of an unequal-span continuous-arch arch bridge. The m-method is applied to consider the combined action of pile and soil, to calculate the anti- push rigidity of group pile foundation,and to simulate the elastic restraint boundary conditions. A three-dimensional model is established by the finite element software to calculate and analyze the carrying capacity and stability of the structure.
