排水固结处理后地基强夯加固的试验研究

Experimental study on improving the drained and consolidated ground with DCM

  • 摘要: 通过对强夯后淤泥层中孔隙水压力场分布的测试 ,分析了强夯加固软粘土地基时孔隙水压力随深度、距离的变化规律 ,研究了强夯后淤泥层中的液化空间的发展 ,由此进一步分析了强夯的有效影响深度及影响范围 ,其结果与采用等效拟静力法计算结果基本一致。提出了应用试验手段选择强夯击数、夯点间距及有效影响深度等强夯参数的方法。

     

    Abstract: By measuring the distribution of pore water pressure field in soft clay during DC,the variation of pore water pressure with depth and time in the foundation of soft clay is analyzed,the development of liquefaction space in muck during DC is studied, and furthermore, the effective influence depth and scope are analyzed in this paper. The results are generally consistent with the results calculated by the method of pseudo static method. A method to choose the number of DC, the spacing of DC, the effective influence depth and other parameters through the experiment is presented.
