Research On Dynamic Behavior Of Anchored Rock Slope Overburden Soil Layer

The problem of stability of anchored slope is always very important in geotechnical problems. Because it not only relating the safety of the highway which is under slope, but also sometimes it relating the property and lives safety of the people under the slope. Therefore, the study of unstable slope support is very important. The anchor as the one that is construction a convenient and affordable way of reinforcement, bolting gets a wide range of applications. The slopes in Yunnan Province and the pit supporting bolting are very widespread supported. In Yunnan Province, the prevalence of shallow soil slope is widely distributed along the highways. Considering the safety of the road, some sections of the slope has been bolting. So, there is no doubt about that the importance of anchoring shallow soil slope stability studies.According to the survey, summing both sides of the road slope slump types and causes of instability. And take one of the typical potential landslide as research. In different conditions, Lagrangian numerical methods were applied to establish the corresponding numerical model to calculate the research anchor of slope stability and its dynamic response. The research was supported by the main conclusions are as follows:①Calculating the potential sliding slope static conditions, slope displacement, plastic zone, shear strain variation in the slope body, study the stability of the slope and comparison site survey results prove conclusion of slope instability, and verifying the accuracy of the numerical calculation.②Design slope reinforcement program, the choice of Bolting and working conditions in combined driving conditions computing research. Transportation vibration anchored slope displacement is small, but the design anchor reinforcement, we must consider the durability of the bolt. Slope vibration response in the body affected by the material of slope, the slope of the body of the bolt axial force and mortar shear stress has increased, and soil and rock at the interface.③Under seismic excitation, opened to traffic on the highway slope lateral vibration more severe than the vertical vibration, and the response peak vibration acceleration changes by the road surface slope somewhere.
