İzmir körfezi kuzey kıyı zeminleri için pekleşen zemin modellerinin kalibrasyonu

Research for new models for expressing the real soil behaviour has been considered by scientists, because of the lack of accuracy of elastic or elasto-plastic models. The majority of these new models tend to define hyperbolical curve behaviour, which is also called ?hardening soil model?.In this study, the hardening characteristics of the sedimentary soils in Northern İzmir Bay area are investigated. The experimental data belong to the site investigation studies that were made for the site fill of the coastal road along Karşıyaka-Alaybey-Bostanlı route. The soil mechanics laboratory data was back analyzed using single hardening model of the Plaxis software so that model parameters are calibrated or classified to give the best fit with the odeometer test results.Although effort has been spend on obtaining analysis results that were in good match with the test data, there were still some scattering in the results. The Janbu method within Plaxis yields a smooth parabolic curve from odeometer results while the data of Northern İzmir bay area resembles more like a detached parabola with two different slopes. Comments are made about the good match and scattering of the finite element analysis results, recommendations are made for future work.
