摘要:
采用抗拔法进行了冷杉根系抗拉强度的实验研究，得出抗拉法可以用于对冷杉根系抗拉强度进行检测，通过采用多种回归模型进行分析比较，求得最佳冷杉根系侧强曲线公式，并取得了较好的应用效果。分析了影响冷杉根系侧强曲线的因素，其中冷杉根系的根径和根长为影响其侧强曲线的主要因素，根系的抗拉强度的大小是根径与根长共同作用的结果。
Abstract:
A research was conducted on pull-out method for determining the strength of Abies fabric root system, a conclusion was reached that pull-out method might determine the strength of Abies fabric root system. Then, a formula for testing strength by regression analysis of several models was obtained with fairly good result. Analyzed the effect factors of Abies fabric root system strength, of which the root diameter and root length are the important effect factors, the interaction of root diameter and root length bring on the strength of Abies fabric root system.
