摘要
概述了近半个多世纪以来国内外有关林木减振控制技术在力学方面的研究。各种技术通过增强土壤-根系统锚固、增大树干刚度或减少树冠作用力来达到树在风载作用下减小振动的目的,但大部分技术都是在半经验情况下发展起来的,缺少必要的力学理论基础。最后,文中提出了树干柔性支撑技术,即安装自制减振器,认为这是一种有效的林木减振控制技术。
This article summarized the research progress of forest tree vibration control technology in terms of mechanics at home and abroad in nearly half century.A range of technologies have been adopted to control tree vibration under the wind load via strengthening the anchorage of the soil-root system,adding the stiffness of the trunk,or reducing the force on the crown structure.But most current technologies have been mainly developed based on visual assessment or personal experiences,lacking the necessary mechanical theories.Finally,flexible strut technology was proposed to be used as a a vibration absorber.This technology is being researched as an effective technology tocontroltree vibration.
