摘　　要：从理论分析着手,详细论述了岩体预应力锚索内锚固段的作用机理与剪应力分布规律,并以大型的岩土工程数值分析软件(ADINA)为研究手段,对预应力锚索的锚固机理进行了数值模拟计算和分析,最后用试验资料加以论证.Starting with theoretical analysis, the action mechanism of prestressed anchor rope and the distrib- uting regulation of shearing strength along grouted part were discussed in detail, and based on the numerical analysis software ADINA for large-sized geotechnical engineering, the action mechanism and the distributing regulation of shearing strength were computed and analysed. At last, lots of experiment data were used to testified the above-mentioned analysis.
