摘　　要：以乐山市金口河大桥为例,通过全桥有限元模型的建立,对该中承式钢管混凝土拱桥进行了荷载试验分析,试验结果表明该桥具有足够的刚度和强度储备,但是桥面T梁的横向连接较弱。Taking the Leshan Jinkou River Bridge as an example,through the whole bridge finite element model supervision,this paper made load test to half-through steel pipe arch bridge,the test results showed that the bridge had enough stiffness and strength reserves,but the transverse connection of bridge T beam was weak.
