摘　　要：红壳竹竹材的物理力学性质与竹龄、竹秆部位均有密切关系。竹材的干缩性随竹龄增加逐渐减少；基本密度、顺纹抗压强度、顺纹抗拉强度和抗弯强度都随竹龄增加而增加，至５～６年生达最大值。竹秆由下至上，含水率、干缩性逐渐减少；维管束密度和基本密度逐渐增加，力学强度亦相应提高。竹材横断面的不同分割对抗压强度有极显著的影响。The physico mechanical properties of culm wood of  Phyllostachys iridenscens go hand in hand with ages and parts of the culm The air shrinkage properties of the culm decrease gradually with the age while the basic density,compression strength parallel to the grain,tension strength parallel to the grain and bending strength increase with the age of the culm and reach their maximum values at the age of 5～6 years From the culm’s bottom up,the water containage and air shrinkage properties reduce while the bundle density,basic density and strength increase And different splittings of the culm have a remarkable effect on the compression strength
