Rock Slope Engineering Materials Testing And Its Applicatiaon Research

In recent years, a number of Southern Shaanxi Expressway construction, which greatly promoted the development of the region. But there are a lot of different types of slope along the Expressway, which geological composition is extremely complex, and there may be many weak slope body Potential slip surface or surface structure, stability is poor. An-kang to Shanxi-Sichuan Boundary Expressway, in the region, there are many large rock slope along the way, which in the summer rainy season, landslides are more likely to occur.Sector for the rock slope conditions along the An-kang to Shanxi-Sichuan Boundary Expressway, this article has carried out the domestic and foreign research and engineering survey,80 many of the slope along the road for a more in-depth analysis and research, and two The probability of a larger landslide slope test analysis. The results of the analysis, one of them a potential landslide slope stability analysis, calculation and evaluation. Main tasks are as follows:(1) through several on-site survey and exploration, combined with the local natural geography and environmental conditions along the slope of statistics and classification;(2) the slope of the rocks on the two laboratory experiments, and the parameters of the physical properties of rocks to evaluated;(3) targeted to potential landslide rock samples under different water content uniaxial compression tests and conventional triaxial test, by obtaining the rock strength parameters of rock strength in a different state changes,that may occur the case of disasters to predict the situation;(4) the potential use of limit equilibrium method of calculation and evaluation of the stability of the landslide, with the simultaneous GPS surface deformation monitoring results were compared and the method of calculation and evaluation and feasibility analysis.
