| The slope engineering is an important part of geotechnical engineering, along with the economic, social and technological development, slope shoring method and continuous development and innovation. Anchor as an important means of support is widely used in geotechnical engineering. Therefore, on the slope stability of reinforcement mechanism and anchor role has important significance to study the mechanism.In a large amount of information and reference on the basis of literature, through theoretical analysis, numerical simulation and experimental research, the scene dynamic monitoring of in situ means of slope reinforcement mechanism and anchor mechanism has carried on the preliminary research. According to theoretical analysis, and through a large finite element software ANSYS numerical simulation, build slope fe models, from the internal strain and stress state of the slope, the actual conditions of different slope stability of the slope excavation, layered process and its secondary anchor process simulation and evaluation.From the practical engineering, the type of slope, economic situation and construction process of determining reasonable supporting schemes, prestressed anchor mechanism, the influence factors of anchor bolting materials, the analysis: embedding dimension, anchor bolt, rock properties and anchor parameters, etc. Through in-situ test and numerical simulation, the method to determine reasonable anchorage calculation results and practical monitoring data is consistent, and meet the design requirements. |
