Assessment of soil improvement and geotechnical studies applied in structures

In this thesis study, ''Geotechnical Methods Applied in the Scope of Ground Improvement Works of Vadistanbul Park'' ground improvement and application of them have been searched and analyzed. Within the framework of the thesis, geology and ground features of the construction site are defined. The necessary arrangements and recommendations for the improvement of the soil were made and the application types, procedures and parameters of the braced and basic remedies were demonstrated using the plaxis program. The design of the test piles before the construction of the system and the determination of the parameters were examined and the success of the application was evaluated with the quality control practices applied during the construction process and afterwards. The applications to be implemented are discussed in detail in order to ensure optimum efficiency in the equipment used in this project. In this study evaluating the methods of soil improvement, it has been taken into consideration that the existing holes in the ground are reduced by mechanical means, the ground holes are filled with various composition mixtures,the groundwater level is powered or the water content of the ground is reduced or various elements are used. In addition, in the scope of the study, the ground conditions in the project area, especially the nonlinear behavior of the grounds in the soil layers which is a significant difference between the sliding modules, load acceptance, nonlinear dynamic analysis of pile foundation under eartquake loads, anchorage load carrying capacity calculations, analysis of the geology and soil properties of the study area, evaluation of the ground profiles of the geotechnical analyzes, inclinometer analysis,information on the drilled holes and geological sections were evaluated. With this study, the effects of the ground conditions on the piles that occured during stresses or a possible earthquake were investigated. Within the framework of the mentioned methods, the numerical results obtained from the underground soil improvement and geotechnical field are combined with the plaxis program and the effects of deformation behavior of the site were investigated in detail.
