Load-displacement behavior of ductile micropiles in cohesive soils
Stoklasová, Andrea ; Račanský, Václav (referee) ; Chalmovský, Juraj (advisor)
This thesis is focused on creation of mobilization curves, based on data, obtained from standard and detailed monitoring of the load test. The load test was performed on the 9 meters long ductile micropile. The first part of the thesis explains the methods and principles, which was used to construct the mobilization curves. Next there is description of the technologies of ductile micropiles and the load test. In the next part of the thesis is generally explained process, which was applied to the evaluated data. For evaluation was used spreadsheet Microsoft Excel and programming language Matlab, with Kernel Smoothing extension. In the last chapter of the thesis there are interpreted the load transfer function together with skin friction and micropile displacement.

Determination of load-transfer functions for bored piles
Čechová, Simona ; Račanský, Václav (referee) ; Chalmovský, Juraj (advisor)
The thesis is consisted of theoretical and practical part. In theoretical part was described nowadays commonly used method for analysis of single axially loaded replacement piles defined by Masopust (1994). There was also explained principle of load transfer method and was done analysis of mobilization curves, which are applied abroad, and finally were defined essential entry parameters for construction of selected load transfer curves. In practical part method by Masopust (1994) was transformed, limit shear stresses and tip resistances were calculated and values of deformation parameters for constructing cubic root curve and hyperbolic load transfer curve were deterined. In the last step both types of load transfer curves were constructed for shaft and pile tip of a replacement pile in different depths in fine-grained soil and in coarse-grained soil.
