Stability Analysis And Protection Measures Of The Heng'er Road In The New Area Between Guiyang And Anshun

The New Area between Guiyang and Anshun, where a road called Heng'er Road.along the road there are many high dig slope.The geological structure of this area is complex.the structure of the rock mass is quite different-A lot of rock slope has potential weak structure plane or slip surface,the stability of rock slope is poor.The stability of rock slope along the road and the optimization of protection will be the major technical problems encountered in the construction process. The main work has the following aspects:(1)With your new local natural geographical and environmental conditions, we have many works on the construction site and along the slope were several detailed survey and classification on the road, to analyze the structural features of the road slope and failure types.Through the preliminary investigation and statistical analysis, the factors that affect the stability of the rock slope are summarized, and the influence factors are analyzed and evaluated in detail according to the actual situation of the slope.(2)Application of numerical simulation software FLAC3D to cross two slope stability calculation and analysis, the analysis results show that no stress concentration distribution, uniform shear strain distribution, plastic zone does not appear obvious, slope as a whole the maximal displacement in 8.8 mm, which indicates that the instability and failure of slope is not going to happen.(3)according to the characteristics of the horizontal 2 sections along the slope, the corresponding protection measures are proposed, respectively, the three dimensional network with the diamond frame masonry protection, KST of plant protection of the climbing plants and a combination of comprehensive protection, and introduces the construction technology for the protective measures.
