Posouzení stability zářezu a návrh sanačních opatření na úseku dálnice D805 km 56,200 – 57,720 km

Abstract

An overview of so far processed exploration work which has covered the territory of construction of the route of highway D-8 part No. 0805 in 56.200-57.720 km is submitted. This territory is affected by landslides deformation. This deformation affected the way of indentation has been designed for the highway in this territory. The course of construction caused slides along cylindrical surface in the highway T-cut in the territory. The total mass of landslides was larger than 11.000 cubic metres. The circular arc analysis was performed in program GEO - 5. The analysis was performed on the basis of the data obtained from so far finished works and from assesment of samples taken directly from the landslides. The way of designing the remedial meassures was based on the stability calculation.
