连续梁拱组合体系桥梁是一种结构受力合理、外形美观、新颖的结构体系,主要受力构件是由纵梁、拱肋、吊杆及拱脚构成.它既克服了传统拱桥巨大的拱端推力,又改善了连续梁桥较大的弯矩和剪力的受力状况,最大限度的发挥了拱梁混凝土和预应力钢筋各自的特点,经济效益显著.该文通过对连续梁拱组合桥某大桥进行成桥静力和动力荷载试验,并将试验结果和理论分析结果进行比较分析,为评价该桥的整体结构性能、验证设计理论和确定结构安全度提供可靠依据.

The continuous beam arch combination system bri-dge is a innovative structural system of structure reasonable fo-rce, beautiful appearance, the main force member is constitute-d by the stringers, rib, boom and the arch. This bridge overca-me the huge arch end thrust of traditional arch bridge and imp-roved the bending moment and shears force status of continuo-us beam bridge;maximize the character of arch beam concrete and prestressed reinforcement and the economic benefits are remarkable. In this article, the author test the bridge static and dynamic loading of continuous beam arch combination, and comparative analysis the test results and the theoretical to pro-vide a reliable basis to evaluate the performance of the bridge structure overal evaluation, to verify the design theory and de-termine the structural safety.
