公路砖石拱桥加固原理及实效分析

Analysis of Reinforce Principle and Effect of Highway Arch Bridges Made of Brick and Stone

以砖石拱桥的加固实例为工程背景,对砖石拱桥原拱圈下增设拱圈、原拱上增设钢筋混凝土拱圈、钢杆件拉结、钢板箍与螺栓锚固等几种加固方法的施工工艺流程、适用范围、注意事项等进行描述和探讨。

The paper expounds several reinforcing methods of arch bridges made of brick and stone on the basis of several arch bridges. It describes and discusses construction technics flow, application range and important notice of several reinforcing methods such as adding arch ring under original arch ring, adding arch ring made of reinforced concrete above original arch, pulling by steel poles, anchoring by steel board hoop and bolt.
