根据美国ASTM D5456《结构复合木材产品评价规范》评价方法标准及美国工程木材协会PRL-501《单板层积材性能标准》，对国产杨木单板层积材力学性能进行了检测和评价分析。通过拟合优度检验，发现杨木单板层积材力学性能与对数正态分布拟合得较好。杨木单板层积材力学性能特征值的研究可为我国结构用单板层积材特征值确定方法提供参考。% According to the evaluation methods and standards of ASTM D5456 Standard Specification for Evaluation of Structural Composite Lumber Products and APA PRL-501 LVL Performance Standard, inspection and evaluation analysis of the mechanical properties of domestic poplar LVL is conducted. Through good-of-fitness tests, it is found that the mechanical properties of poplar LVL fit lognormal distribution very well. The study of the characteristic values of the mechanical properties of poplar LVL provides a reference for the methods for determining the characteristic values of China's structural LVL.
