| 摘 要： | 通过对来自福建建瓯试验地16个毛竹种源竹材的密度、顺纹抗压强度、顺纹抗剪强度、顺纹抗拉强度和弦向抗弯强度及其弹性模量等物理力学性质的初步研究,结果表明:竹材物理力学性质在各种源之间存在一定的差异,其中湖南株洲的毛竹竹材物理力学性质比于其它种源的毛竹要好,而安徽霍山的毛竹竹材的物理力学性质较差,测量的各指标中有基本密度、抗剪强度、抗拉强度三项指标都达到最低;竹材密度的大小、抗拉强度的高低随种源纬度的降低而呈降低的趋势,而竹材的抗剪强度呈与之相反的趋势。

| Abstract: | Through the preliminary study of the bamboo density,compressive strength parallel to grain,shear strength parallel to grain,tensile strength parallel to grain,tangential bending strength,elastic modulus and other physical and mechanical properties from 16 provenances of Moso bamboo in the test place of Fujian,Jian'ou,it was showed that there were some differences among different provenances in the physical and mechanical properties.The culms from Zhuzhou,Hunan had better physical and mechanical properties than other provenances,while the culms from Huoshan,Anhui had the lowest basic density,shear strength and tensile strength.The bamboo density and tensile strength tended to decrease with the decrease in latitude,while the bamboo shear strength showed the opposite tendency. |
