Abstract

It is one of the most important problems to judge anchoring force of constant resistant bolt in anchoring support. This involves the properties of rock, binder and bolt material as well as the interaction among them in the process of stress. In this paper, a series of numerical experiments have been carried out by using the software "Real Failure Process Analysis (RFPA)", which is suitable for the study of complex mechanism of nonlinear and discontinuous media. Four factors that affect the anchoring force of constant resistance bolt are analyzed, the whole process of mechanical failure of anchored rock with constant resistance bolt is monitored, and the failure mode of anchored rock under different conditions is revealed. Draw a few conclusions with reference significance.

摘要

判断恒阻力螺栓在锚固支座中的锚固力是最重要的问题之一。这涉及岩石，粘合剂和螺栓材料的特性，以及它们在应力过程中的相互作用。在本文中，使用“真实故障过程分析（RFPA）”软件进行了一系列数值实验，该软件适用于研究非线性和不连续介质的复杂机理。分析了影响恒阻力螺栓锚固力的四个因素，监测了恒阻力螺栓锚固岩体的力学破坏全过程，揭示了不同条件下锚固岩体的破坏方式。得出一些具有参考意义的结论。
