摘　　要：介绍国内首座钢箱混凝土拱桥在特种荷载 NHL- 330 7非公路自卸车作用下的荷载试验 ,并以程序 SAP5和考虑了钢箱对混凝土约束作用的程序 CFSB对试验结果进行了分析。结果表明 ,钢箱混凝土中混凝土受箍作用明显 ,该构形式受力合理 ,刚度大 。The experimental test on concrete filled steel box arch bridge which is the first bridge in China is presented under the special type load NHL 3307. The numerical results of the test is analyzed by general program SAP5 and program CFSB in which the steel box restriction for the concrete is taken into account. The results indicate that the steel box has a good restriction for the concrete in steel box, the force distribution of its structure is reasonable and its rigidity is very bigger.
