Numerical analysis of deep foundation pit excavation based on Moore-Coulomb
In order to study the influence of Moore-Coulomb model and its parameters on the simulation of deep foundation pit deformation and ensure the safe construction of foundation pit in the construction process, the finite element analysis method is used to analyze the change of Moore-Coulomb model in the simulation of deep foundation pit in the excavation process. By comparing and analyzing the actual monitoring results, the applicability of Moore-Coulomb model to simulate the deformation of deep foundation pit is obtained. The results show that in the prediction of ground settlement, settlement displacement of surrounding buildings, horizontal displacement and vertical displacement of piles, there is little difference between the predicted value of Moore-Coulomb model and the actual monitoring value, and the variation trend of each project simulation value of Moore-Coulomb model under different reference stress is the same as the actual monitoring value. The research conclusion reveals that the Moore-Coulomb constitutive model under different reference stress has certain reference value for the prediction of deep foundation pit excavation deformation.
