Abstract

V originále

The aim of this publication is to highlight some selected case studies that relate to issues of interaction of the geological environment with engineering construction. This is an issue of flysch sediments, karst areas, liquefied sand, loess sediments and basalt rocks. This geological environment is causing many problems. This can cause problems during the construction process, or in trying to preserve the long life of these constructions. Mentioned problematic rocks can complicate future or existing construction through landslides, low bearing capacity, differential settlement, karstification, filtration faults and many other disorders. Labelling the rock as problematic rock is debatable. Each geological environment is affected by a large amount of geofactors. These geofactors input to deciding about the appropriateness or unsuitability of the foundation soil and their risks. Generally, the unsuitability of the foundation soil is determined by a combination with geofactors such as ground water, earthquakes, sloping terrain and many others. Therefore, it is necessary to designate “problematic rocks” understood as an environment with many problems. That means problems with foundation engineering and existing constructions at a high rate. This designation also includes an environment where the consequences of construction failure have unforeseen consequences. Problematic rocks also include soft rock, which is dedicated to a number of other publications. Although each environment is completely unique, learning from mistakes and lessons learned from other countries is very important.
