土的动力特性分析方法探讨

Discussion on Analytical Methods of Dynamic Characteristics of Soil

针对土的动力特性传统分析方法的局限性,讨论了应用微细观结构动力分析方法分析土的动力特性的必要性,从土的微细观结构入手,提出分析动力荷载作用下土体与建筑物基础共同作用的分析方法是离散单元法与有限单元法相结合的数值分析法.最后,探讨了求解土动力学问题的方法.

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 view point 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.
