Al2 O3陶瓷环在锚具退锚中的应用研究

摘要

A ceramic ring with high compressive strength and brittle under impulse load between anchor plate and anchor ring was added to make the anchor system safe and convenient when unloading the cable bolts. The finite el-ement analysis software ABAQUS was used to analyze the stress level of ceramic ring,and the results were com-pared with ballast test. Analysis and experiment results show that the reasonable design of ceramic ring can be used in a convenient back anchor system.%通过在锚垫板和锚环间添加一个耐压且冲击易碎的陶瓷环，使锚固系统在退锚作业时安全便捷。应用有限元分析软件ABAQUS对结构中陶瓷环的应力水平进行分析，并与陶瓷环的压载试验比较。分析和实验结果表明设计合理的陶瓷环能在方便退锚的锚固系统中使用。
