梁式桥是应用最广泛的一种桥梁结构。随着预应力技术的应用,梁式桥的跨度已达到250m以上,常见的梁式桥跨度在200m以内。梁桥结构型式梁式桥一般包括简支梁、连续梁、悬臂梁、刚构、桁梁,以及其他结构梁式桥梁如V型墩、竖向提升、竖向旋转、水平旋转桥梁。简支梁桥简支梁桥是墩顶上梁体不连续的桥梁结构,梁体一端布置固定支座,另一端布置活动支座以适应梁体温度
Beam bridge is the most widely used type of bridge structure. With the application of prestressing technology, the span of beam bridge has reached over 250m, and the span of common beam bridge is within 200m. Beam bridge type beam bridge generally include simple beams, continuous beams, cantilevers, rigid frame, truss beams, and other structural beam bridge such as V-shaped piers, vertical lifting, vertical rotation, horizontal rotation bridge. Simple-supported beam bridge Simple-supported beam bridge is the pier top beam body is not continuous bridge structure, one end of the beam layout fixed bearing, the other end of the movable support arrangement to adapt to the temperature of the beam
