基于无损检测技术的某木结构门楼检测鉴定

Inspection and appraisal of the timber archway based on non-destructive testing technology

对某木结构门楼开展了检测鉴定,采用了微钻阻力法和应力波相结合的无损检测法对木构件的缺陷进行了定量的检测评估,通过现场取样以及实验室检测的方法,对木材强度等级进行了评定,采用有限元软件对门楼结构的承载能力进行了计算分析。综合检测数据和计算结果对门楼进行了结构安全性鉴定,为该门楼的后续修缮和加固提供了技术支撑。

The article introduced the safety inspection and appraisal of the timber archway.The non-destructive testing method combining the drilling resistance testing method and the stress wave testing method,was used to quantitatively detect and evaluate the defects of the wooden components.Through on-site sampling and laboratory testing methods,the timber strength grade was evaluated,and the bearing capacity of the timber archway was calculated and analyzed by the finite element method.Comprehensively combining the testing data and calculation results,the structural safety appraisal of the timber archway was carried out,which provided technical support for the subsequent repair and reinforcement of the timber archway.
