强夯法加固大面积素填土与液化土地基应用研究

The Application Research of Dynamic Consolidation for Large Foundations of Plain Fill and Liquefied Soil

依据强夯法的加固机理,对拟建住宅小区大面积素填土和液化土地基进行强夯处理。通过平板荷载、标准贯入、静力触探、重型动力触探及室内土工试验研究对比,分析结果验证了强夯法处理此场地地基的适用性与设计参数选取的合理性。研究成果对加固相关素填土与液化土地基工程具有重要的指导意义。

According to the reinforcing mechanisms of the dynamic consolidation, the proposed residential community foundation of plain fill and liquefied soil was constructed by adopting dynamic consolidation method. And then, the ex- perimental results of plate loading test, standard penetration test, static cone penetration test, heavy dynamic penetration test and laboratory soil test were compared and analyzed, which proved that the practice was applicable for this foundation and the selection of design parameters was reasonable. The research results will provide some guidance for the consolida- tion construction of similar plain fill and liquefied soil foundations.
