Abstract

However, in most civil and sensitive geotechnical projects, the Moore-Columbus behavioral model is used due to the simple acquisition of soil mechanical parameters and relatively accurate analyzes, while the Moore-Columbus (MC) behavioral model is used due to complete elastoplastic behavior and uniform loading difficulties. And loading in the stress-strain diagram has computational angles, so in the future in important geotechnical projects such as urban excavation, more advanced behavioral models should be used to express soil behavior. In this research, using a numerical study, an urban excavation that MC behavioral model has been analyzed and implemented with more advanced behavioral models such as hardening soil behavioral model and hardening soil model with softening strains and Finally, these two behavioral models are compared in evaluating the amount of urban good displacement and urban excavation floor elevation. In the continuation of this research, the effects of each of the different soil parameters on the evaluation of soil structural elements in two behavioral models of hardened soil and hardened soil with softening strains with the MC model are investigated. This research is a small step to use more advanced behavioral models in projects used in the country.
