ANALYSIS OF A SLOPE DEFORMATION OF THE D11 MOTORWAY CUT

This diploma thesis consists of a research and a practical part. The research part summarises the problem of slopes movements. The practical part deals with the determination of the slope deformation causes, at the 76th km of the D11 motorway. Causes determination was based on laboratory tests of soil samples taken from the disrupted motorway cut, made at PřF UK soil mechanics lab. Tests of grain size composition were done, plasticity of the L 26 sample was determined and critical strength of the reconstituted L26 and L27 samples was found out in the Translational apparatus box. Soils were categorized due to the according standards and the acquired data were evaluated. In the BricsCAD software, a well arranged locality situation and the slope deformation crosscut underlayed with the geophysical ERT cut were illustrated. In the GEO5 software, slope stability models were created using the Spencer Method of Slices. The slip surface and the groundwater level during the disruption were determined. The practical part also covers a proposal of a remediation appropriate for this deformation and it's modelling in GEO5. For the remediation, the slope stability level is determined. The work is based on the specialized literature, articles, research reports and standards. Powered by TCPDF (www.tcpdf.org
