Monitoring of settlement of embankment subsoil
Karlín, Petr ; Novotný, Jan (advisor) ; Kudrna, Zdeněk (referee)
: During each transport buildings are used embankments, therefore it is important to carry out a detailed geological survey. The task of the survey is to determine the soil properties (soil) for such embankments, bridges and other objects depend on the load. For many objects is undesirable reduction embankment over time, this phenomenon is mainly caused by the consolidation of underlying layers. Parameters find out from the engineering-geological survey is calculating for better prediction of settlement which is based on the value of consolidation. In the following monitoring is measured by change in soil elevation relative to a reference point. These values are further processed and compared with the calculation. Main aim of this work is to unify the addiction values of loading, settlement and time for 90% consolidation.

Secondary raw materials for construction and recultivation of averse impacts of anthropogenic activity on the environment
Suchomelová, Leona ; Kudrna, Zdeněk (advisor) ; Slomek, Jiří (referee)
This work concern utilization of waste in order to produce secondary raw materials and its trying to describe the possible applications of these materials in the best way to meet the economic and ecological requirements. It contains a brief description of the characteristics of secondary raw materials, which have the greatest benefit for use in the construction, which are especially large volume raw materials produced from industrial waste. It focuses mostly on fly ash, slag produced by blast furnace and steelworks and waste produced in construction sites. Use of secondary raw materials are divided on production of raw materials produced from fly ash and slag, on construction of roads, where it's possible to apply large volumes of fly ash, slag and other secondary materials, and construction and reclamation of waste dumps and wasteponds. It also concerns negative influence of secondary raw materials to the environment, levels of pollutants in solid and the water extract.

Modern alternate types of sealing barriers analysis for landfills
Matoušová, Jana ; Sedláček, Jaroslav (referee) ; Kudrna, Zdeněk (advisor)
People and waste on our planet is constantly increasing, and so despite the unattractiveness topic the landfills are the current and noticeable issue. This paper deals with the standards and laws relating to landfills, from which they depend for the creation and construction. I should present an overview of the different variants of application materials to the construction of the landfill could be used, and today sealing landfills are available for engineers. But just I do not engage in alternative sealing options as well as standard which are still widely used methods of sealing landfills. To the situation in the Czech Republic stated in a global context, I give examples of coping with the landfill in other countries such as Chile, where they try to use local raw materials. What is landfill waste and security are concerned; our model may be one of our neighbours - Germany, which in this part is devoted to most extensively. Each of these options has its pros and cons. I leave at will and view of each reader to evaluate the advantages and disadvantages of each solution. It is also possible to adhere to the already proven and well used ways of depositing, in their modernized and improved form.
