深圳龙岗国际自行车赛场木材鉴定及材性分析

A Study of the Wood Properties from International Bicycle Race-field in Longgang of Shenzhen City

对深圳龙岗国际自行车赛场的木材进行树种名称鉴定和木材材性测试分析,结果表明,赛场木材为坤甸铁樟和铁樟;坤甸铁樟的差异干缩、吸水率、体积湿胀率皆小于铁樟,木材尺寸稳定性好;坤甸木材强重比高,材质优。这些研究结果可为深圳市龙岗国际自行车赛场的验收及其他建筑结构材、重型构件、家具、造船、工业用地板等用材提供科学依据。

Wood identification and wood properties from international bicycle race-field in Longgang of Shenzhen eity have been carried out and investigated. The results indicate that two species identified were Eusideroxylon zwageri Teijsm. ＆ Binnend. and Eusideroxylon malagangai Sym. respectively, ratio of tangential to ratial shrinkage, water-absorbing rate and volume swelling rate of Eusideroxylon zwageri are less than those of Eusideroxylon malagangai, dimension stability and ratio of strength to specific gravity is higher for Belian species compared to other tree species. These studies provide scientific basis for the acceptance of international bicycle race-field of in Longgang of Shenzhen city and reasonable utilization of timbers for construction, furniture, flooring, shipbulidig etc.
