Method for testing frictional resistance of arch bridge support
The invention discloses a method for testing frictional resistance of an arch bridge support. The method comprises the following steps: mounting a reaction frame on the top of a first main pier; a jack is arranged between the counter-force frame and the arch foot structure mounted on the longitudinal sliding support; the jack is pressurized for the first time, so that the longitudinal sliding supports mounted on the first main pier and the first side pier generate displacement towards the midspan direction, and the load of the jack at the moment is recorded; pressurizing the jacks for the second time to enable the longitudinal sliding supports mounted on the first main pier and the first side pier to generate displacement towards the midspan direction, recording the load of the jacks at the moment, and then calculating the structural rigidity of the arch bridge; the jack slowly returns oil, so that the longitudinal sliding supports mounted on the first main pier and the first side pier generate displacement opposite to the midspan direction, and the load of the jack at the moment is recorded; the jack is completely unloaded and removed; and the total frictional resistance of the longitudinal sliding supports installed on the first main pier and the first side pier is calculated. According to the method, a reliable basis can be provided for smoothly completing girder closure construction of the arch bridge.
本发明公开了一种拱桥支座摩阻力的测试方法，包括：第一主墩的顶部安装反力架；在反力架与安装在纵向滑动支座上的拱脚结构之间设置千斤顶；第一次给千斤顶加压，使安装在第一主墩和第一边墩上的纵向滑动支座产生向跨中方向的位移，记录此时千斤顶的荷载；第二次给千斤顶加压，使安装在第一主墩和第一边墩上的纵向滑动支座产生向跨中方向的位移，记录此时千斤顶的荷载，再计算拱桥结构刚度；千斤顶缓慢回油，使安装在第一主墩和第一边墩上的纵向滑动支座产生背向跨中方向的位移，记录此时千斤顶的荷载；千斤顶完全卸载并撤除；计算安装在第一主墩和第一边墩上的纵向滑动支座的总摩阻力。本发明能为顺利完成拱桥的主梁合龙施工提供可靠的依据。
