摘　　要：对小变形条件下竹席竹帘胶合板的弯曲力学特性进行研究,构建了竹席竹帘胶合板纵、横向载荷与应力、应变及挠度之间关系的数学模型,与实际数据拟合较好。这对解决竹席竹帘胶合板在实际应用中的弯曲变形问题具有一定的指导作用,也为深入研究竹席竹帘胶合板的力学特性提供了一定的实验基础。Bending mechanical properties of bamboo-curtain plywood under tiny deformation condition are studied and some mathematic models reflecting the relationship between transverse and longitudinal loads of bamboo mat plywood ＆ bamboo curtain plywood and stress, strain and deflection are constructed. All the models match actual data, which is helpful for the solution to bending deformation problems with bamboo-curtain plywood in practical application and some experimental basis will be provided for further study of mechanical properties of bamboo-curtain plywood.
