预应力混凝土公路桥梁开裂现象分析

Analysis on Cracking Phenomenon of Prestressed Concrete of Highway Bridge

预应力混凝土桥梁因其优越的工作性能和跨越能力,被广泛应用于公路桥梁领域,但其在荷载、环境等因素的作用下仍会产生裂缝,影响工作性能和耐久性.论文就预应力混凝土桥梁产生裂缝的原因进行简单分析,并从设计的角度提出相应的建议,以期为设计人员提供参考.

Because of its superior performance and crossing ability, prestressed concrete bridge is widely used in the field of highway Bridges, however, under the action of load, environment and other factors, cracks still occur, which affect the working performance and durability. This paper makes a simple analysis of the causes of cracks in prestressed concrete bridges, and puts forward corresponding suggestions from the design point of view, in order to provide a reference for designers.
