摘　　要：The effects of lay-up layer numbers on laminated bamboo bundle board’s physical and mechanical properties and connection performance were analyzed.The results show that under the conditions of same layer numbers,along with the increase of the lay-up directions,the bending strength,bending modulus,compression strength and horizontal shear strength of the laminated board showed a downward trend,while using non-single direction lay-up structure,the board’s waterproof property was lower than that of single lay-up board, but the board’s connection performance was raised. Therefore,in the real application,with the condition of guaranteeing the mechanical properties of the board to meet operating requirements,the lay-up directions should be increased to improve the board’s connection performance and to increase the board’s safety.The effects of lay-up layer numbers on laminated bamboo bundle board’s physical and mechanical properties and connection performance were analyzed.The results show that under the conditions of same layer numbers,along with the increase of the lay-up directions,the bending strength,bending modulus,compression strength and horizontal shear strength of the laminated board showed a downward trend,while using non-single direction lay-up structure,the board’s waterproof property was lower than that of single lay-up board, but the board’s connection performance was raised.
