从钢筋混凝土套箍封闭主拱圈加固技术和拱上建筑减载的方法入手,阐明了加固减载法的机理及其特点,并结合依托工程说明了该法在石拱桥加固处治中的应用,通过分析比较石拱桥采用加固减载法处治前后的承载能力,说明综合加固处治技术是行之有效的。
This article starts with the method of reinforcing the main arch ring by the ferrule and the method of reducing the load on the arch building. The mechanism and characteristics of the load - shedding method are illustrated. The application of the method in the reinforcement of the stone arch bridge is illustrated with the support engineering. By analyzing and comparing the carrying capacity of stone arch bridge before and after treatment by using the method of reinforcement and load shedding, it is proved that the comprehensive reinforcement treatment technique is effective.
