Abstract:
Based on soil mechanics and geo-dynamics principle the wave theory of the vibroflotation dynamic method during improving foundation was studied. The wave equation of vibroflotation dynamic method is derived according to stress-strain relationship and effective stress principle. The increasing rule of pore-water pressure of vibroflotation dynamic method, i.e. the differential equation of pore-water pressure accumulation and solving condition, is investigated. The research result shows that the increasing rule of pore-water pressure is wavelike and relative to frequency of vibration, and which could be used to calculate the liquefaction depth of soil layer and the improvement depth of dynamic compaction method. The effect of Rayleigh wave is also discussed.
