摘　　要：基于高烈度地震条件下深水水库库区桥梁施工的复杂条件,针对高烈度库区修建连续刚构桥梁面临的问题和挑战,围绕连续刚构桥用于高烈度库区存在的技术瓶颈,首次提出了桩柱式连续刚构桥结构体系,并用数值分析方法解析了其受力特性,论证了该结构体系的合理性,证明桩柱式连续刚构桥结构体系在高烈度地震条件下深水水库库区条件下具有结构优势和推广应用价值。The characteristics of bridges in deep water reservoir area under high seismic intensity condition are analyzed.The problems and challenges of the continuous rigid frame bridges which are constructed in those area are studied.Focusing on the technical bottleneck of these bridges in high seismic intensity reservoir area,the structural system named"pile-column continuous rigid frame bridge"is proposed for the first time,and its mechanical characteristics are analyzed by numerical analysis,the rationality of this new structural system are verified.It is proved that the pile-column continuous rigid frame structure system has its structural advantages and value for further application promotion in deep water reservoir area with high seismic intensity.
