摘　　要：基于全寿命设计理念,对某长江通道桥进行概念设计。在桥型方案比选的基础上,提出钢管混凝土主梁斜拉桥(主桥)和大跨度波折钢腹板组合箱梁连续刚构体系(辅桥)的组合结构桥梁的方案构思,以期使该桥具有较好的全寿命周期性能。Based on the life cycle design conception, the conceptual design of a Changjiang River crossing is made. Through comparison of alternatives for the crossing type, the considerations of a composite structure incorporating a cable-stayed bridge with concrete-filled steel tube main girder （for main bridge） and a long span continuous rigid-frame box girder system composited with corrugated steel webs （for auxiliary bridge） are proposed in order that the crossing should have better life cycle performance.

关 键 词：组合结构 斜拉桥 连续刚构 桥梁设计 全寿命设计
