多种地基处理方式在滨海软基回填场地中的综合使用方案

摘要

在一个大面积软基处理场区内,对地质情况、场地使用功能进行详细划分,有针对性地选择强夯、强夯置换、堆载预压等不同地基处理方式,应用于不同区块以形成综合方案.此方案在保证施工可行、满足使用要求的前提下,较单一处理方法可实现大幅节省投资的目的.通过工程实施和检测结论,验证并总结不同地基处理方式的适用条件.%A large area of soft soil foundation is divided into several blocks according to the geologic conditions and the application function.Different ground treatment methods such as dynamic compaction,dynamic replacement,stacking preloading are selected to be applied to different blocks and form a comprehensive solution.On the premise of ensuring construction feasibility and satisfying the application requirement,the single solution can cut down greatly the investment.Based on the engineering implementation and testing conclusion,we summarize the adaptable conditions of different means for ground treatment.
