以河南省信阳市西关桥为依托,对其进行了混凝土碳化深度、强度、纵向挠度以及静载试验等,所得数据利用旧桥校验系数法对其进行承载能力评定,为该桥的加固提供依据,为类似的旧桥检测、承载力评定与加固提供参考。采取有效的检测加固措施,确保旧桥安全运营,我国桥梁建设养护和管理工作才能真正步入“建养并重”的可持续发展道路。
Based on Xiguan Bridge in Xinyang City, Henan Province, depth, strength, longitudinal deflection and static load test of concrete were carried out. The obtained data were evaluated by the old bridge calibration coefficient method to provide the reinforcement for the bridge Based on this, it provides a reference for the similar detection of old bridges and the assessment and reinforcement of bearing capacity. To take effective testing and reinforcement measures to ensure the safe operation of the old bridge, the bridge construction maintenance and management in our country can truly enter the “sustainable development with equal emphasis”.
