岩石膨胀头锚杆锚固参数模拟研究

Simulation Analysis on the Anchorage Parameters of the Expansion Anchor Head of the Rock Bolt

利用Abaqus有限元软件,对膨胀头锚杆进行数值模拟,通过改变膨胀头锚杆的长度、直径和埋置深度等锚固参数,对比分析了不同锚杆锚固参数对膨胀头锚杆极限抗拔承载力的影响。通过模拟分析,确定了膨胀头锚杆抗拔力影响最有效的锚固参数。本研究可为今后膨胀头锚杆的设计提供可靠的依据,同时也为施工提供相关的经验,确保工程后期的安全性。

The paper use Abaqus finite element software to simulate the anchor with expansion head, through changing the anchorage parameters as length, diameter and buried depth etc. of expansion head of the bolt, analyzes the influence of these different parameters on the ultimate uplift capacity of the anchor. Through analysis, the most effective parameters of the anchor with expansion head are determined. This study can provide a reliable basis for the design of the anchor with expansion head in the future, provide relevant experience for the construction, and ensure the safety of the laterperiod of the project.
