Abstract:

The thesis deals with the load test of piles and subsequent analysis of monitoring in
comparison with design methods for determining the ultimate load curve.
The first part of the thesis describes the load test itself and monitoring in the form
of standard strain gauges and three loops of fiber optic sensors. This part includes
an analysis of the theoretical principles of the design methods used to determine
the ultimate load curve.
The second part focuses on the evaluation of the measured monitoring data and
the analysis of the calculation methods used to determine the ultimate load curve.
The methods were selected based on the differences in the theoretical basis for the
calculations. The aim was to analyze the differences between the individual
approaches for the given geological conditions.
Finally, a comparison of all the methods used is presented, first between each other
and then with the evaluated monitoring of the load test performed.

Process of defence

Bc. Petr Juračka obhajoval diplomovou práci s názvem "Zhodnocení dostupných metod pro stanovení mezní zatěžovací křivky pilot na základě podrobně instrumentované statické zatěžovací zkoušky". Po prezentaci práce a přednesení posudků vedoucího a oponenta práce reagoval na jejich dotazy a připomínky a poté na tyto otázky: Jaký vliv má hodnota modulu pružnosti betonu na výsledky? Byla pilota pažena a v celé délce? Měnil se její průměr? Jaké hodnoty vykazovaly moduly pružnosti betonu reálně? V rámci obhajoby diplomové práce odpovídal student výborně.
