摩擦套箍法在超限荷载下桥梁加固中的应用

Application of friction hooping method in reinforcement of bridge under over-limit load

论述了使用摩擦套箍法加强老旧桥梁承载力的方法及其原理,并通过某电站大型设备在运输过程中,超限荷载安全通过经过该法加固过的桥梁的工程实例,表明了此法对老旧桥下部承载力的临时加固特别是对盖梁承载力提高方面有较好的应用价值。

The application of the friction hooping method in reinforcement of old bridge bearing capacity and the principle of the method were described. Through a practical example of a large scale equipment of a power station which passes the bridge reinforced with the method under over-limit load during transportation process, it shows that temporary reinforcement of lower part bearing capacity of old bridge with this method has good application value especially for improvement of bent cap bearing capacity.
