补充资料:刚构桥
刚构桥 rigid frame bridge 主要承重结构采用刚构的桥梁。梁和腿或墩(台)身构成刚性连接。按结构形式可分为门式刚构桥、斜腿刚构桥、T形刚构桥和连续刚构桥。①门式刚构桥。其腿和梁垂直相交呈门形构造,可分为单跨门构、双悬臂单跨门构、多跨门构和三跨两腿门桥。前三种跨越能力不大,适用于跨线桥,要求地质条件良好,可用钢和钢筋混凝土结构建造。三跨两腿门构桥,在两端设有桥台,采用预应力混凝土结构建造时,跨越能力可达200多米。②斜腿刚构桥。桥墩为斜向支撑的刚构桥,腿和梁所受的弯矩比同跨径的门式刚构桥显著减小,而轴向压力有所增加;同上承式拱桥相比不需设拱上建筑,使构造简化。桥型美观、宏伟,跨越能力较大,适用于峡谷桥和高等级公路的跨线桥,多采用钢和预应力混凝土结构建造。如安康汉江桥(铁路桥),腿趾间距176米,1982年建成。③T形刚构桥。是在简支预应力桥和大跨钢筋土箱梁桥的基础上,在悬臂施工的影响下产生的。其上部结构可为箱梁、桁架或桁拱,与墩固结而成T型,桥型美观、宏伟、轻型,适用于大跨悬臂平衡施工,可无支架跨越深水急流,避免下部施工困难或中断航运,也不需要体系转换,施工简便。④ 连续刚构桥 。 分主跨为连续梁的多跨刚构桥和多跨连续-刚构桥,均采用预应力混凝土结构,有两个以上主墩采用墩梁固结,具有T形刚构桥的优点。但与同类桥(如连续梁桥、T形刚构桥)相比:多跨刚构桥保持了上部构造连续梁的属性,跨越能力大,施工难度小,行车舒顺,养护简便,造价较低,如广东洛溪桥。多跨连续-刚构桥则在主跨跨中设铰,两侧跨径为连续体系,可利用边跨连续梁的 重量使T构做成不等长悬臂,以加大主跨的跨径。
