摘　　要：云南小湾大桥为主跨130m的中承式钢箱提篮拱桥,介绍了该桥静载试验的主要内容和测点布置以及理论计算的方法等项目,并给出了特种活载(汽-86,挂-300)试验中的2个主要工况的理论与试验结果对比值,最后得出了有益的结论。The Xiaowan Bridge in Yunnan is a half-through basket handle arch bridge of steel box type with a main span 130 m. In this paper, the major items of static load tests, layout of measurement points and calculation methods for the Bridge are presented. The comparison values of theoretic calculations and tests of two kinds of loading cases in special live load tests (Vehicle-Grade 86, Platform Truck Weighing 300 Tons) are provided, and some helpful conclusions are drawn as well.
