摘要
强夯法地基加固技术在国内外获得了广泛的应用。通过对国内外强夯法的加固机理、有效加固深度、孔隙水压力的增长与消散规律的回顾,总结了强夯法加固地基技术中的三个关键因素的研究现状。并着重论述了强夯技术的最新进展-强夯联合井点降水技术在加固饱和淤泥质软粘土地基中的应用,最后提出了强夯研究中存在的问题及发展方向。
Nowadays, dynamic consolidation method （DCM） has been widely used in the treatment of foundation at home and abroad. By giving a review of the reinforcement mechanism of dynamic consolidation, the effective reinforcement depth and the laws of increasing and decreasing of pore water pressure, the research situation of three key factors in dynamic consolidation method have been summarized. What＇s more, the latest technical progress about dynamic consolidation technology on saturated soft soft- DCM combined with well dewatefing has been discussed with emphasis in this paper. Finally, the existing question and trend in study are pointed out.
