The Stability Research of Highway Bedded Rock Slope Based on the Stress Monitoring

Article Preview

Abstract:

Research on the problem to process the stability of bedded rock slope of monitoring, deformation monitoring were carried out difficulty .This paper carrying out the stress monitoring method to evaluate it. Use the strength reduction FEM to reach the slope failure location with different structure planes distance, and use the theory and project test of blot stress monitoring to verify. The result of the project test shows that the slope stress were tend to stability about 60 days after cut,the bolt maximum force value were 57.6 MPa,meet the requirement of reinforced design tensile strength,the test result shows that this slope tend to stability.
