锚喷混凝土加固桥梁施工简介

锚喷混凝土加固旧桥的方法是“新奥法”隧道施工法在桥梁加固中的应用，其原理是通过新增加混凝土与受力钢筋和原结构紧密结合，组成喷射混凝土（含钢筋网）-锚杆-原结构的整体组合结构。既阻止了结构继续变形位移和开裂，又充分发挥原结构的作用，共同承受外荷载作用。该文对锚喷混凝土加固桥梁的施工工艺进行了介绍，可供桥梁加固的工程技术人员参考。

Brief Introduction of Anchor Spraying Concrete Reinforced Bridge Construction

The method of anchor spraying concrete reinforcement of old bridge is the application ofNew Austrian Methodtunnel construction method in the reinforcement of bridge.Its principle is that the newly added concrete combines with the bearing steel bar and the original structure to form the integrated combined structure of the sprayed concrete(including steel bar net)-anchor arm- original structure,which not only prevents the structure from continuously deforming,displacing and cracking,but also fully plays the ...
