无损检测技术在木拱廊桥保护中的适用性探讨

Applicability Exploration of Non-Destructive Testing in the Protection of the Timber Arch Lounge Bridge

木拱廊桥主要分布在闽浙两省交界山区,由于容易受到腐朽和微生物侵害的影响,木构件损伤现象普遍.而无损检测作为一种非破坏性检测手段,广泛应用于国内外木构建筑和古木的保护研究,它是在对原有结构形式不破坏或微破坏的前提下,查勘木材物理力学性质状态的新型检测手段.结合木拱廊桥保护工作,研究并比较了适用于木拱廊桥的无损检测技术,提出建议,为评价古廊桥安全性能和建立完整的检测与保护体系提供参考.

The timber arch lounge bridges are mainly distributed in the border of Fujian and Zhejiang provinces. The damage of wood component in the bridge was widespread due to the susceptibility to decay and microbial a non-destructive testing method, Non-Destructive Testing damage. As （NDT） is applied in the protection of Timber Architecture and Ancient Wood. It is a new testing method to check the physical and mechanical properties of wood without destroying or destroying the micro-under the premise. Thus, combined with the features of the timber arch lounge bridges, the paper described and compared the Non-Destructive Testing techniques which was suited for the timber arch lounge bridge, gave recommendations, and provided references for evaluating safety performance and establishing a complete detection and protection system.
