The significance of the transport infrastructure is going strongly up during last period. It is connected with two aspects. Firstly the interest is connected with energy consumption as about 40% of overall consumption is consumed for transport infrastructure. Secondly the interest is focused on securing the serviceability of transport infrastructure also during nonstandard conditions. Between these conditions belong not only cases elicited by human factor, as transport for example the blockade caused by transport accident, but also by cases elicited by external factors, mostly by natural hazards. The paper is focused on securing serviceability during natural impacts ‐ hazards. Floods, landslides, rock falls are natural hazards typical for middle Europe. Therefore natural hazards like tsunami, typhoons, hurricanes typical for coastal zones, or avalanches typical for alpine zones, respective earthquakes for seismic prone zones are not included in. The paper is therefore focussed in more details on the interaction of transport infrastructure with floods, landslides and rock falls with the main aim to guarantee at least limited serviceability during such events. In doing so the view of geotechnical engineering is playing primordial task.
BIM “Building Information Model” creates a significant step forward in the whole process of construction. The role of geotechnical engineering will be shown as for classical building engineering so for civil engineering structures. In the first case all upper structures are in interaction with ground (subsoil), when foundation structures are basic element of this interaction. The 3D Ground model and 3D Foundation structure model create therefore one of the first individual parametric elements around basic (coordinating) BIM model. Some specificity will be shown as the impact of step by step creation (nD dimension) of the Ground model for the earliest building conception. Roughly the same is valid for civil engineering structures. Some specificity will be shown for earth structures of transport engineering, as a selection of borrow pit, definition of soil compaction for fill, fill compaction or any other methods of soil improvement and its control as they create important elements for the safe and optimal embankment design and performance. Final 3D Ground model together with 3D Geotechnical structure model (real performance) create the important base for the future decision making, when some changes will occur.
The digitization process has been going very fast lately as well BIM modelling, as both are strongly connected. The paper briefly evaluates this process from different levels, with the main focus on the conceptual level. The 3D geotechnical model of the ground comes to the fore, as this ground plays an important role also in the process of the BIM because practically all building structures are situated on this ground. Since the EN 1997 Geotechnical design also uses geotechnical and computational models, their connection with the BIM process is very useful and brings new possibilities. Especially from the point of view of connecting the design of the superstructure with substructure and ground and thus the presentation of the result in BIM model of the whole building. BIM models are presented not only for foundation structures, but also for earth structures and their advantages are shown, especially from the view of the decision-making process, as in the design and implementation phase so in throughout the service life of the building.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
