Properties of alluvial sediments at Albertov, Prague
Chvílová, Martina ; Boháč, Jan (advisor) ; Lešner, Jeroným (referee)
Bachelor thesis deals with the sediments of river terraces in Prague, Albertov. On these sediments from the deep drill hole J6 in campus Albertov area I made eight grain measurements, processed grain curves and normatively classified terrace soils with classes S1, S2, S3 and F3, F4. They are sandy soils partly containing fine gravel or fine fraction admixture. I also performed the grain analysis on soils 1,5m deep in near morphological distance from the drill hole on which bases I searched for analogy between sediments on campus Albertov building site. They are recent soils of local and foreign digged material. In documented terrace material with S2 character was observed that with content of fine- grained fraction under ca. 5% the increase of the proportion of fine-grained admixture elevates the angle of sands natural slope.

Engineering geological and geotechnical problems of foundation of highly loaded floors in hall buildings
Chvílová, Martina ; Novotný, Jan (advisor) ; Šmejkalová, Tereza (referee)
This diploma thesis deals with geological, engineering geological and geotechnical aspects of founding (grounding) of large industrial floors. It shows typical reasons, which can cause the problems during and after the construction on the floors of hall objects. The first part of this thesis presents authors own simple classification of conditions, which are connected with construction of hall floors. The second part contains two sets of commented case studies. The short case studies in the first set originate from literature research. In the second set author presents cases that have been visited and assessed by herself. In the third part of this thesis is on the base of three numerical models shown, how the character of the subsoil affects settlements of large, heavy loaded floors. Models were created in Plaxis 2D programme.
