Abstract


Prediction and control of the excessive settlements are very important in the design of different structures. In recent decades, many ways of prediction of settlement have been developed by researchers. Using soil models via numerical methods for prediction of soil behavior is one of the newest of them. In this regard the critical state models have been used widely for this purpose. The Modified Cam-clay model is an elastic plastic strain hardening model that is based on Critical state theory. This model is used in geotechnical engineering practice. Nevertheless, due to some reasons using of this model is in doubt for practical issues. In this paper, a pair of circular and rectangular footings has been modeled via finite-element method and Modified Cam-clay model in a case study. In the next step, the predicted and monitored settlements of these footings were compared. Finally, relatively good and conservative performance of Modified Cam-clay theory is shown in practice, as the main aim of this paper.
