Pitfalls in Generating an Engineering Geological Model, Using a Landslide on the D8 Motorway near Dobkovičky, Czech Republic, as an Example

Popis výsledku v původním jazyce

The variability of ground conditions resulting from different types of rocks with a varying origin, degree of weathering, tectonic deformation, hydrogeological conditions, and other factors poses considerable problems for engineering geological model generation and the subsequent analysis of rock mass behaviour. The authors demonstrate, through a case study of the D8 motorway in the Czech Republic, the problems that can occur during construction if the engineering geological model generation is not applied correctly during construction. It demonstrates the importance of the conceptual model and its application at the beginning of the project. The case study is also used to present experience with an observational engineering geological model generation. The simplification of the complex geological setting represented the key problem of the observational model generation for engineering purposes. The authors critically assessed the available archive data, the ability to generate 3D models using various software (RockWorks, GMS), and transferring engineering geological model to simulation software (MIDAS GTS NX). It is very demanding to construct the geometry of individual lithostratigraphic units and to define quasi-homogeneous engineering geological units based on their characteristic values for the simulation of the slope stability of the rock massif.
