摘要
根据桥址处的地形、地貌、地质、水文、气象的要求,赫章特大桥推荐方案主桥采用(96+2×180+96)m预应力混凝土连续刚构桥,比较方案主桥采用(140+322+140)m预应力混凝土斜拉桥,着重介绍了大桥的结构构思、桥型、桥墩及基础结构形式的选择。
According to the requirements of terrain, landforms, geology, hydrology and meteorology in the site of bridge prestressed concrete continuous rigid frame bridge （96 ＋ 2 × 180 ＋ 96）m is recommended for main beam scheme of Hezhang super large Bridge. The other compara- tive scheme prestressed concrete cable-stayed bridge （140 ＋ 322 ＋ 140）m is also mentioned. In the end structural design concept, selection of bridge shape, pier and types of abutment are mainly introduced for Hezhang super large Bridge.
