摘　　要：钢管混凝土拱桥是我国近年来桥梁发展的新技术,笔者详细介绍了松原市中承式钢管混凝土拱桥荷载试验情况.通过荷载试验,检验桥梁整体受力性能和承载力是否达到设计要求,实验内容包括:静载试验,测定试验孔的静应变、静挠度,计算校验系数,验证该桥工程质量的安全可靠性;通过动载试验,测定试验孔的动力响应,以检测其在动态荷载作用下桥梁的受力状态,通过试验及计算,表明桥梁能够满足使用要求.Concrete filled steel tube arch bridge is a new technology in the bridge development of China, this paper has introduced the loading experiment of middle bearing concrete steel tube filled arch bridge in detail. The experiment will check whether or not the bridge reach the design standard, including：static loading experiment, detecting static stain, static deflection, calculating checking coefficient, and checking the reliability of engineering quality. Dynamic responding was detected with dynamic loading experiment, the result of calculation has proved that the bridge can satisfy design requiremenlt.
