Abstract
Plate load test is widely used for bearing capacity and settlement calculations of foundations. In this study, 6 plate load tests were carried out to determine the bearing capacity and settlement of the foundation. High-speed railway project will be constructed in related area. The project location is in Ankara/Turkey. Bearing capacity of the station platform building foundation was determined according to plate load test and finite element analysis. Finite element analysis (FEM) software, Plaxis 2D, was used for the understanding of the settlement behaviour of soil. Soil strength and deformation parameters were determined according to plate load test and finite element analysis. Elasticity theory was used for analytical solutions. Field measurements, finite element analysis (FEM) results and analytical solution were compared at final of the study. Finite element analysis (FEM) and elasticity theory settlement calculation results have a strong correlation with field observations.

Abstract
Plaka yükleme deneyi temel taşıma gücü ve oturma hesaplarında yaygın olarak kullanılmaktadır. Bu çalışmada yapılan 6 plaka yükleme deney verisi kullanılarak taşıma gücü ve oturma hesapları yapılmıştır. Deneylerin yapıldığı bölgede yüksek hızlı tren hattı inşa edilecek olup proje lokasyonu Ankara’ dır. İstasyon peron yapısı temelleri için sonlu elemanlar yazılımı ve plaka yükleme deney verileri kullanılarak taşıma gücü hesapları yapılmıştır. Zemin oturma davranışı sonlu elemanlar analiz program Plaxis 2D kullanılarak modellenmiştir. Zemin dayanım ve deformasyon parametreleri plaka yükleme deneyi ve sonlu elemanlar yöntemi ile belirlenmiştir. Analitik çözümler için elastisite teorisi kullanılmıştır. Çalışmanın sonunda plaka yükleme deney sonuçları, analitik çözüm ve sonlu elemanlar çözüm sonuçları karşılaştırılmıştır. Sonlu elemanlar ve elastisite teorisi ile hesaplanan oturmaların arazi ölçümleri (plaka yükleme deneyi sonuçları) ile güçlü bir korelasyon oluşturduğu görülmüştür.
