摘要
随着对古树名木的保护愈加受到重视,古树管理保护技术也在逐渐更新优化。目前,国内对有缺陷的古树名木主要采用刚性支撑防护,但长期使用刚性支撑会破坏树木的自适应能力,不利于古树力学平衡。为减少刚性支撑带来的问题,广州中山纪念堂对园内的2株白兰古树应用“眼镜蛇拉索系统”进行拉索牵引,以提高树木结构稳定性。基于对白兰古树的风险评估结果,从现状出发,对具有风险的分枝进行有针对性的拉索系统技术设计,并对比经历台风“苏拉”“海葵”所带来的强暴风雨前后拉索的应用情况,发现白兰古树各拉索点没有脱落或偏移,验证了“眼镜蛇拉索系统”的安全性。
With the protection of ancient and famous trees receiving more and more attention,the management and protection techniques of the trees are also being gradually updated and optimized.At present,rigid propping is mainly used to protect ancient and famous trees with defects in China.However,long-term use of rigid propping will damage the adaptive ability of trees,which is not conducive to the mechanical balance of ancient trees.In order to reduce the problems caused by rigid propping,Sun Yat-sen Memorial Hall in Guangzhou adopted a'Cobra Cabling System'for two ancient Michelia×alba in the park to improve structural stability.Based on the results of risk assessment of the trees and the current situation,the technical design of the cabling system for branches at risk was carried out.Comparing the application of the cabling system before and after the strong storm brought by Typhoon Saola and Haikui,it was found that there was no dislodgement or deviation of cabling points on the trees,which verified the safety of the cabling system.
