摘要
针对李小庄桥质量严重破损的工程事故,首先运用多种检测法对其混凝土强度进行了鉴定:在外观检测的基础上,利用超声—回弹综合法和超声波法进行了微观检测、微观分析,有效地提高了检测的准确性;然后用结构强度理论进行应力分析;最后综合分析了此桥的破损原因。此研究可为工程检测、破损分析及应采取的安全措施提供一定的参考。
In order to get the cause of a bridge's damage,several detection methods are used:Based on the appearance observation,firstly,ultrasonicrecovery synthetical method and supersonic flaw detecting are used to progress microcosmic detection;secondly,using structural strength theory,we got its mechanics analysis;in the end,the causes of the bridge's damage are analyzed synthetically.This article can offer paradigm to the engineering detection,damage analysis and the safety facility to the bridge.
