摘要安徽霍山县靠近毛竹天然分布的北部边缘，其独特的地理位置及气候条件影响着毛竹材的各项特性，其中海拔是影响毛竹材力学性质的重要因子。以安徽霍山不同海拔（设120、230、370、510和600 m 5种海拔处理）的毛竹材为试验材料，研究了海拔因子对竹材力学性质的影响。结果表明：海拔因子对霍山毛竹的竹材密度有一定影响，随海拔升高，竹材的气干密度和全干密度呈增大趋势，但差异不大；海拔因子对竹材的顺纹抗压强度和顺纹抗剪强度有显著影响，但对顺纹抗拉强度影响不大。霍山毛竹材的各项力学特性接近传统的建筑用木材，经过合理加工可以替代传统木质建筑材料。
Abstract：Houshan County in Anhui Province is at the proximity of the northern edge of natural moso bamboo forests. Its unique geographic location and climate condition affect the various properties of moso bamboo, while the altitude is the determining factor influencing the mechanical properties of moso bamboo. The study took the moso bamboo timber from different altitudes in Houshan, including 120, 230, 370, 510 and 600 m, as the experiment materials, to understand the influences of the factor of altitudes on mechanical properties of bamboo timber. The results showed that the factor of altitudes has certain influence over the density of moso bamboo in the county, and as the altitudes increase, the air dried density and oven dry density of the bamboo timber increase, but with slight difference. The altitudes have significant influence on the compression strength and shear strength parallel to grain but only have slight influence on the tensile strength paralleled to grain. The various mechanic properties of moso bamboo timber produced in Houshan is similar to the traditional constructional timber, which indicates that moso timber could be the substitute of the traditional construction timber after reasonable processing.
