Zajištění dálniční mostní opěry v rozsáhlém a hlubokém sesuvu

Abstract

Due to the mountainous relief, the construction of highways in Slovakia encounters several geotechnical problems and this diploma thesis deals with the section of the highway where the route runs through a landslide area near the village of Lisková. The work briefly describes the possibilities of construction in landslide areas and numerical modelling using the finite element method. To create a realistic numerical model, it is necessary to obtain input parameters based mainly on engineering geological surveys and geotechnical monitoring. The protective structure of the bridge abutment, consisting of stability shafts and a stabilization basin, was modelled in the Midas GTS NX program. The stability of the slope was assessed by the method of reduction of strength parameters.
