| Abstract [eng] |
The final master's project analyzes the installation of the automobile roadbed. The aim of the work is to carry out a research and multi-criteria assessment of the technologies for the installation of road embankments using the MOORA method. The final project consists of three parts. The first part describes the aspects of roadbed installation, describes the necessity of roadbed research. The second part describes the research methodology. Laboratory investigation of static load plate test, price structure, machinery labor demand, human labor demand, expert survey reliability and multi-criteria MOORA evaluation calculations. The third part describes the research carried out, which analyzes four different types of roadbed: roadbed installation with cement, roadbed installation with geosynthetics, roadbed installation with lime, roadbed installation without additives. Evaluative alternatives are presented and the most rational option is selected using the MOORA method. Alternative priority lines were determined according to the indicators of the price of roadbed installation, working time of mechanisms, working time of people, technological break, soil bearing capacity. After evaluating the updated normative documents, the maximum bearing capacity and the results of the multi-criteria evaluation, the research object I, in which roadbed improved with 2% cement, is the most effective solution. Scope of work 68p., 21 tables, 27 pictures, 72 literature sources. |
