| 摘 要： | 以宁波某实际工程为例，介绍了有限元分析在强夯法加固回填土地基中的应用．通过对不同夯击能作用下加固深度和竖向沉降的分析，结合Menard经验公式和规范方法，在验证有限元分析合理性的基础上起到指导工程设计的作用．研究表明，有限元方法能较好的模拟回填土地基在强夯冲击荷栽作用下的动力响应，本文对有限元方法在强夯地基处理中的应用具有参考价值．

| Abstract: | In this paper, a practical project in Ningbo was taken as an example to describe the apphca- tions of finite element analysis dynamic consolidation of backfill in the land - based. Through the action of differ- ent reinforcement tamping energy deposition depth and vertical analysis, combined with empirical formulas and norms Menard method, finite element analysis verified on the basis of rational engineering design played a guid- ing role. Studies showed that the finite element method is capable of simulating the dynamic response of dynamic compaction backfill soil foundation under impact loading. |
