摘要： 为了解某地基稳定性及地基的承载能力，对场地地基土层、地质岩性等结合不同作业点之间的联系与区别作了深入对比分析，通过方案比选，选择强夯法作为其最终的地基处理方法，采用规范填料对地基夯实加固有明显的效果，建议填料应严格按照设计要求选用且合理地增加触探作业点。

Abstract: This paper presents a case study of soil improvement and testing project for the tobacco leaf re-roasting and storage sites of Hongta Group in Yuxi City. The subsurface soil/rock conditions and their geotechnical properties are evaluated. Based on the analysis, the deep dynamic compaction was selected as the soil improvement method. It is concluded that the dynamic compaction with standard backfill material can significantly improve the subsurface soils. It is also suggested that the dynamic penetration test as the quality assurance tool is appropriate and the testing locations should be representative.
