【摘要】 本文以珠海某地基处理工程为例,围绕强夯法地基处理设计思路中的关键问题进行了探讨.系统归纳了强夯法动力密实、动力固结、动力置换3种主要方法的机理特点和适用性.基于工程实例,详细分析了地基处理场区的地质情况,并以软土分布规律为依据进行了合理性区域划分,针对不同分区确定了相应的强夯地基处理方法,采用应力面积法和有限元方法对地基沉降计算进行了对比分析,阐述了地基加固效果检测在信息化施工及优化设计中的重要性.更多还原

【Abstract】 This paper discusses several key problems around the design idea of dynamic consolidation by taking a project of foundation treatment in Zhuhai as an example; gives a systematical introduction on the mechanism and application of three major dynamic consolidation methods i.e.dynamic compact,dynamic consolidation and dynamic replacement; has a detailed analysis on the geological condition of foundation treatment area,which was divided reasonably according to the distribution of soft soil,based on practical project.Relevant foundation treatment methods of dynamic consolidation were designed by regional division.Meanwhile,the foundation settlement calculation results of stress area method and FEM were compared and well coincided with each other.The paper finally emphasizes the importance to test the treatment effect on information construction and optimization design.更多还原
