强夯法在处理吹填土地基工程中的应用

曹妃甸吹填土全部为近两年吹填形成的饱和粉细砂,填土厚度大、面积大,固结时间短,液化等级较严重。工程前期通过对比,决定了采用在本工程中有很好的经济效益与技术优势的强夯法。该文对采用强夯法处理后的曹妃甸吹填土地基性能进行了检测,检测结果分析表明强夯法处理粉细砂吹填土效果良好,并能很好的消除液化。

Application of Dynamic Consolidation Method in Dredged Fill Foundation Engineering

All of the Caofeidian foundation is dredged fill formed of saturated silty-fine sand in recent two years,the dredged fill is deep and distributed in large area,with short solidification periods and severe liquefaction grade.By comparison in the earlier stage construction periods,dynamic consolidation method is adopted to treat the Caofeidian dredged fill foundation with good economic benefits and technical superiority.The test results show that the dynamic consolidation raises the bearing capacity of the foundation distinctly and eliminates the liquefaction well.
