Study On Stability And Reinforcement Technique Of Rock Bedded Slope Of Zhu-cheng Road

Layered slopes included: The level slopes, bedding slopes and inverse slopes, in which bedding slopes are destroyed early. As to bedding slopes, at present the collapsing mechanism, the stability appraises and the project designs were preliminary researched at home and abroad, certain cognition was gotten, but still not put studying achievement into actual project with good effects.Firstly stability effect factor of bedding rock slopes were summarized; secondly, according to structure pattern bedding rock slopes were classified, and destroying models were discussed; subsequently some stability analysis methods of bedding rock slopes were introduced, applicability and merits and faults of these methods were analyzed; then the engineering design of bedding rock slopes were studied, engineering design technological process and 10 design advice were summarized, which was easy to guide engineering design and construction. In the end research production were applied in slopes of Zhucheng highway K82-K83, after stability analysis appraisal of this slopes with stereographic projection methods and FLAC3D numerical value simulation methods, wholly grouted bolts supporting system was put forward to unsteady crisscrossing slope.
