摘　　要：结合实际工程进行深层真空振击法加固吹填软土的现场试验,主要对土体的Ps值、含水率、压实度、塑性指数、颗粒级配和地基承载力等物理力学指标进行测试。通过对加固前后这些数据的对比分析研究地基土的强度增长特性。经过处理,吹填土的地基承载力及压实度达到了设计要求。证明该方法的可行性与实用性,说明该方法在吹填软土地基处理方面具有广阔的应用前景。This paper makes a field trial of deep vacuum rapping reinforcing of the dredger fill, mainly on the physical and mechanical characteristics such as value Ps of soil, moisture content, degree of compaction, plasticity index, the particle size distribution and bearing capacity, etc. The foundation＇s bearing capacity and the degree of compaction of dredger fill meet the design requirements after treatment, which demonstrates the feasibility and practicality of this method and proves that this method will have broad application prospects in reclamation soft processing.
