刚构桥刚构桥rigidframebridge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。重庆长江大桥：T形刚构公路桥
