Stability Analysis and Reinforcement Protection of Slope at a Tunnel Portal on Mudanjiang-Suifenghe Railway |
| |
| Abstract: | Taking protection and reinforcement works of the high slope on the left of a tunnel portal on Mudanjiang-Suifenghe Railway as the background, the paper on the basis of the geological conditions made contrast analysis on the physical and mechanical parameters and back-calculated index of the slip soil obtained from laboratory test, and then determined the physical and mechanical parameters of the weak structural plane of slope. Next, with GEO-SLOPE software, the stability in different cases was calculated and, with technical and economic comparison, the slope protection and reinforcement measures were determined to guarantee the stability of slope at the tunnel portal. |
