预应力混凝土具抗裂性好,刚度大;节省材料,减小自重;提高受压构件的稳定性;提高构件的耐疲劳性等优点,被广泛应用于高层建筑、公路、铁路桥梁。本文主要介绍了预应力桥梁质量控制的一些要点和注意点。
Prestressed concrete with good crack resistance, large rigidity; save material, reduce self weight; improve the stability of the compression member; improve the fatigue resistance of components, etc., are widely used in high-rise buildings, roads, railway bridges. This paper mainly introduces some key points and points of attention in the quality control of prestressed bridges.
