马尾松学名pinus massonina tamb,华南一带称为青松,山松或本松,广东广西叫做枞树,福建叫做枞柏。原产在东南各省,现在华东、华中、西南各地都有较丰富的产量这种树的主干很直,高的可达30公尺,粗的直径可达1.6公尺。成长速度很快,人工培植,20～30年即可成材。马尾松木质坚硬,富油质,但容易腐朽及虫蛀,因此在工程上很少应用。一般都把它用来培养茯苓或采取松脂,甚至砍来做柴烧。过去很少有人对它的物理力学性质作系统的研究。解放以来,随着国家建设事业的发展,木材需要量日益增大,马尾松的利用问题也引起了人们的注意。为了使这种木材能在公路建设事业中发挥它的作用,有必要系统的研究它的性能。从1954年起,公路材料试验所(现已改为公路科学研究院筹备 Pinus massonina tamb, the scientific name of Pinus massoniana, is called Qingsong, Shansong or Bensong in southern China, Eucalyptus in Guangdong and Guangxi, and Phyllostachys praecox in Fujian. It is native to the southeastern provinces and now has abundant production in various parts of East China, Central China, and Southwest China. The main trunk of this tree is straight, with a height of up to 30 meters and a diameter of up to 1.6 meters. It grows quickly, artificially cultivated, and can be grown in 20-30 years. Masson pine is hard and rich in oil, but it is susceptible to decay and infestation, so it is rarely used in engineering. It is generally used to cultivate oysters or to take turpentine, and even cut it for firewood. In the past, few people systematically studied its physical and mechanical properties. Since the liberation, with the development of national construction, the demand for timber has been increasing. The use of masson pine has also attracted people’s attention. In order for this wood to play its role in highway construction, it is necessary to systematically study its performance. Since 1954, the Highway Materials Testing Institute (now the Road Research Institute
