我国公路桥梁承载能力检测评定技术的现状与发展

目前我国公路桥梁承载能力评定主要依据1988年颁布的《公路旧桥承载能力鉴定方法(试行)》进行,该方法对于桥梁检算的规定过于原则化,对承载能力检算系数的取值规定过于专家经验化,因此,我国现有的公路桥梁随载能力鉴定主要是基于荷载试验的评定方法。在1988年评定方法的基础上,提出了基于检测结果、通过检算分析评定桥梁随载能力的新方法体系。

Status and Development of Inspection and Assessment Technology of Bridge's Load-bearing Capacity in China

At present hte assessment to bearing capacity of highway bridge is based on Certificate Mehod to Load-carrying Capacity of Former Highway Bridge(on trial),issued in 1988 in China.In the method,the check adheres principle and the determination criterion of checked factor of load-carrying capacity is based on specialist experience too much.So the existing load-carrying capacity certificate is mainly based on the assessment method of loading test.In light of the assessment issued in 1988,the new system of assessing bearing capacity of highway bridge is presented according to inspection result and checking analysis.
