ABSTRACT
The slope optimization design economized RMB12,000,000 Yuan than the former reinforcement design. Because the rock mass of the slope is weakness and fragmented, and the slope is very high and steep, and the reinforce measure carried on very great optimization, some technical personnels and experts queried the long-term safety of the slope. The long-term safety of highway slopes in mountain areas with complex geological conditions has a direct relation not only to the safe operation of the highway itself, but also to the life and wealth security of the people who live along it. The bolt force was comparatively small and tended to be stable. All of these indicated that the bolts had a good effect on supporting the slope and the structure was safe. The surface of bolt and shotcrete support is intact, and the slope’s surface is well-drained so that no accumulated water exists.
