摘　　要：20世纪六七十年代,江苏北部地区成功从意大利引种美洲黑杨,在国内通称为意杨。经过几十年的发展,国内意杨资源相当丰富,由意杨原木生产的旋切板胶合木(简称LVL)在多个领域得到广泛应用,但鲜见用于建筑结构。因此,对意杨LVL材料物理力学性能进行研究,以期拓展意杨LVL在建筑领域的应用。结果表明,意杨LVL材料物理力学性能优且变异小,可用作建筑结构的承重材料。In the 1960 s and 70 s,the northern part of Jiangsu province successfully introduced North America black poplar from Italy,now known as poplar in China.After decades of development,the domestic poplar resource gets quite rich and the laminated veneer lumber（called LVL for short） made from poplar log has been widely used in many fields,but rarely in building structures.Therefore,authors of this paper study on physical and mechanical properties of poplar LVL materials,so as to expand the application of it in the field of architecture.The results show that the physical and mechanical property of poplar LVL materials is good and has small coefficient of variation,which can be used as structural materials.
