摘要
本文对振冲碎石桩加固饱和粉土地基进行了较为全面的试验研究。对振冲加固的各个过程的振动孔压进行测试分析,包括成孔阶段、成孔后的动孔压消散、复振效应、上下留振阶段、成桩阶段以及加固前后的动孔压对比等。得到一些结论性意见可供设计施工参考。
A research program of strengthening of saturated silty soils by vibro replacement stone columns was conducted, including measurement of dynamic pore water pressure during each stage of vibroflotation, such as stage of inserting vibroflot, dissipation of pore pressure after sinking down to the design depth, effects of repeated vibroflotation and the stage of forming stone column, and some parametric analysis. Wave velocity method for determining effectiveness of densification of vibroflotation and some comments are presented.
