摘　　要：深厚软土地区的地基处理投入高,病害多。特别是刚柔相接段是病害的高发部位。文章以横沥岛尖开发项目为依托,研究并提出解决深厚软土地区地基处理中刚柔过渡问题的方法。笔者采用调查法分析本地软土的特点、刚柔相接的类型、处理的经验、设计原则、不同的处理方案,通过数值分析法获得不同方案的处理结果,进一步分析不同类型条件下,不同方案各自在工期、工艺、处理效果、施工难度、造价等方面的优势,针对不同的过渡类型提出推荐处理方案,形成了一套深厚软土地区不同刚柔相接类型的处理办法。通过对本套办法的应用,在将来可进一步研究其有效性,其最终成果将对深厚软土地区的刚柔过渡设计起到很好的指导作用。In deep soft soil area,the investment in foundation treatment is high,and there are many diseases.In particular,the rigid-flexible section is the high-risk part of the disease.Based on Hengli Island Tip Development Project,this paper studies and proposes a method to solve the rigid-flexible transition problem of foundation treatment in deep soft soil areas.The author adopts the survey method to analyze the characteristics of the local soft soil,the type of rigid-flexible connection,the experience in treatment,the design principles,and different treatment schemes.The processing results under different schemes are obtained by numerical analysis.Then it further analyzes the advantages of different schemes in terms of construction period,technology,treatment effect,construction difficulty,cost,etc.under different types of conditions,and proposes recommended treatment schemes for different transition types.A set of treatment methods for different types of rigid-flexible connection in deep soft soil areas have been formed.Through the application of this set of methods,its effectiveness can be further studied in the future,and the final results will have a good guiding significance for the design of rigid-flexible transition in deep soft soil areas.
