摘　　要：通过动力排水固结法处理饱和软粘土地基现场试验测试数据,寻求动荷载作用下饱和软粘土的孔压和变形的发展规律,发现同一深度土体超静孔隙水压力的消散与变形具有一致性关系。对动力排水固结法加固淤泥类软土地基的作用机理研究和工程实践具有指导意义。According to the experimental data of soft clay foundation treated with dynamic consolidation by drainage, the laws of pore water pressure and deformation of saturated soft clay under dynamic loading are discussed. The relation between the excess pore water pressure dissipation and vertical settlement increasement is founded. These discussions provide some useful conclusions for study on the principle of soft clay compacted with dynamic consolidation by drainage, and it is significant to engineering projects.
