空心板桥梁加固前后荷载试验分析及加固措施研究

Load test analysis and reinforcement measures of hollow slab bridge before and after reinforcement

目前在我国的现役城市桥梁中,桥梁病害日益严重,需要对这些结构的安全性进行检测,如承载能力不能满足要求,需对桥梁进行维修加固设计。通过对某空心板桥梁进行了全面的外观检测和静载试验,分析病害原因,提出维修加固措施。验证了该加固方法的可靠性,可为今后空心板类似病害的加固提供参考。

At present,in China's active city Bridges,the bridge disease is increasingly serious,it is necessary to test the safety of these structures,such as the bearing capacity can not meet the requirements,need to carry out maintenance and reinforcement design of the bridge.In this paper,the appearance of a hollow slab bridge is examined and the static load is tested.The reliability of the method is verified,which can provide reference for the future reinforcement of similar hollow plate diseases.
