| Abstract: | 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. |
