Research on Numerical Simulation of Modified Coefficient of Bearing Capacity of Composite Foundation
As an effective foundation treatment method,composite foundation can give full play to the potential of foundation soil and reinforcement,and is widely used in engineering.In view of the shortcomings of the current theoretical research on the ultimate bearing capacity of composite foundations,this paper focuses on the sand pile composite foundation,mixing pile composite foundation,and concrete pile composite foundation,which are widely used in engineering.The finite difference method was used to establish the numerical model.Firstly,the rationality of the numerical model was proved by comparing the calculated value with the theoretical value.Then,the ultimate bearing capacity and failure mode of the composite foundation were analyzed.The influence of different reinforcement depths,reinforcement spacing and reinforcement strength on the ultimate bearing capacity of the composite foundation was compared,and the variation law of the correction coefficient of the ultimate bearing capacity of the composite foundation was obtained.
