摘　　要：参照美国标准ASTM D 5764-97a(2007),探讨测试方法、层板等级、钢销直径和加载方向对日本落叶松(Larix kaempferi)胶合木销槽承压强度的影响。单因素方差分析结果表明,影响日本落叶松胶合木销槽承压屈服强度的因素依次为:层板等级>钢销直径>加载方向,测试方法对承压性能的影响不显著。Glulam samples made of Larix kaempferi wood were made and tested according to ASTM D 5764-97a（2007）. The following effects on dowel bearing strength were analyzed： test method, laminate grade, bolt diameter and loading direction. The influence factor order ranked by importance on dowel bearing was as follows.- laminate grade〉bolt diameter〉 loading direction. Test method had no influence on dowel bearing strength.
