摘　　要：指出连续刚构桥因其跨越能力强得到广泛应用,但其悬臂状态的稳定问题较突出,针对某三跨连续刚构桥施工阶段最大悬臂状态进行稳定性分析,得出相关结论以期指导同类结构工程施工。This paper points out the reason of continuous rigid frame bridge applicated widely is its overstrength spanning capacity, but the stability outbursted on its cantilever state. As focalling on such state, it makes an analysis of stability on the most big cantilever state of three-span continuous rigid frame bridge＇s construction. Concluding the eorresponding conclusion to guide the similar structural engineering oonstructions.

关 键 词：连续刚构桥 悬臂状态 稳定性
