摘要:
 利用Fakopp应力波检测仪对北京市古建筑中较常使用材落叶松、琼楠、杉木进行检测，结合统计学中置信区间估算方法，处理应力波仪检测出的应力波在健康材料中的传播速度，总结出一套古建筑木构件现场缺陷检测的应力波传播临界速度的计算方法，期望利用此方法建立一个应力波速度检测依据，使在今后现场检测当中能快速、准确判断出古建筑木构件中是否存在缺陷及缺陷的位置，以便进一步的检测。
Abstract:
 The stress wave test technology has a wide range of application in internal defect detection of the wood parts in ancient architecture.A stress wave measuring equipment,Fakopp was adopted to carry out the test on 3 woods that were conventionally used in ancient architectures in Beijing,including larch (Larix gmelinii),nanmu (Beilschmiedia), and fir (Cunninghamia lanceolata).Comparing with the those which were measured with defects free materials,the obtained data were processed by a statistic method, confidence interval,a set of calculation methods for the defect detection was summed.It was hoped to extend this methods for a quick and accurate on-site detection of the defects in wood parts for ancient architecture.
