摘要
锚杆支护基岩土工程中常用的一种支护形式,对锚杆支护机理的研究,不同作者曾采用过多种方法。本文提出了以锚杆拉拔试验确定锚杆轴力及粘着力的理论方法,并结合边界元法对锚杆支护的的机理进行数值模拟。文中给出的算例表明,本文提出的方法计算机实施简单,结果与实际符合较好。
Rauthors have investigated the mechanism of rockbolting using various methods.A theoretical consideration is developed for determining the axial and coherentforces for rockbolts, based on the rockbolt's pulling experiments. Numericalsimulation of the rockbolting mechanism has been conducted by using thetheoretical results combined with the boundary element method. The exampleincluded shows that the proposed method is simple in computer implementationand that the results are well coineided with those in practice.
