| 摘 要： | 对于高烈度地震区大跨桥梁的设计推荐了一种全新的桥式方案——空腹式箱梁连续刚构，该结构是钢管桁架和预应力混凝土板的组合结构。与常规钢桁梁及混凝土连续刚构桥相比，该组合结构具有较大的优势，是一种极具潜力的桥梁结构形式。

| Abstract: | The author recommends a brand new long-span bridge structure in high intensity earthquake areas--consecutive box girder rigid frame bridge with hollow abdomen. The structure is a kind of combined structure with steel tube truss and pre-stressed concrete board. Compared with normal truss bridges and consecutive concrete rigid frame bridges, the structure has many advantages and it is really a new bridge structure with great potentials. |
