有限元法在模拟强夯施工过程中的应用研究

Application of Finite Element Method in the Construction of Dynamic Compaction Simulation

强夯法是我国目前地基处理中采取的一种主要加固方法,因其具有高应力、动荷载、瞬时性的特点而受到广大人员关注。文章主要通过有限元数值模拟的方法,基于MIDAS/GTS有限元软件对强夯过程中的荷载施加过程以及施工后的地基土的变形进行了相关研究,结果表明有限元法能很好的模拟落锤瞬间时地基土的动力响应,对类似工程有借鉴意义。

Dynamic compaction is one of the main reinforcement methods adopted in the foundation treatment in China, and it is concerned by people because of its characteristics of high stress, dynamic load and instant character. Based on the finite element numerical simulation method and the MIDAS/GTS finite element software, this paper studies the loading application process in dynamic compaction and the deformation of foundation soil after construction.
