公路桥梁施工中的体外预应力加固技术分析

On external prestressed consolidation technique in road and bridge construction

介绍了公路桥梁施工中体外预应力加固原理,简述了体外预应力加固的技术优势,主要从放样定位、锚固点设置、张拉预应力筋等方面,阐述了体外预应力加固施工要点,有利于该技术的推广应用。

The paper introduces the principle for the external consolidation in road and bridge construction, indicates the technical advantages of the external prestressed consolidation, and illustrates the construction points for the prestressed consolidation from the sampling position, alloca-tion of anchorage location, and tension prestressed reinforcement, so as to extend its application.
