| Abstract: | Aiming at the limitations of traditional analytical methods for the dynamic characteristics of the soil,the necessity of the application of microstructure dynamic analysis method to analyze the dynamic characteristics of the soil was discussed,and from the viewpoint of the soil microstructure,the numerical analysis method was proposed for analyzing the interaction between soil and the foundation under the dynamic loads,which was the discrete element method combined with the finite element method.Finally,the method was discussed to solve the dynamic problems of soil. |
