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。
A commonly used support form for rock bolt support base geotechnical engineering. Different methods have been used by different authors for the research on bolt support mechanism. In this paper, a theoretical method to determine the axial force and adhesion of the anchor rod with the pull-out test of the anchor rod is proposed. The numerical simulation of the bolt support mechanism is carried out by combining with the boundary element method. The examples given in this paper show that the method proposed in this paper is simple to implement and the results are in good agreement with the actual ones.
