摘要
古树在经历过数百年后会存在不同程度的安全隐患,构成这些安全隐患的缺陷称之为强度缺陷,它们降低了古树抵抗风雪荷载的能力。本文将古树的强度缺陷归结为三种类型:腐朽空洞、结构缺陷、枯伤裂纹,并从树木力学的角度分析了强度缺陷如何影响古树的强度和稳定性,阐述了古树的破坏方式及其力学机制,以期为古树保护与修复提供借鉴和参考。
Having lived for hundreds of years,there may be different degrees of safety risks in ancient trees.The defects that constitute these safety risks are called strength defects,which reduce the ability of ancient trees to resist wind and snow loads.In this paper,the strength defects of ancient trees are classified into three types:holes from decay,structural defects,and dead cracks.A mechanical analysis was also made on how the strength defects affect the strength and stability of ancient trees with an elaboration on the damage modes and mechanical mechanism,so as to provide reference for conservation and restoration of ancient trees.
