摘　　要：在强夯置换砂桩加固填海地基工程中,对强夯砂桩施工过程中超孔隙水压力变化的监测是十分必要的.通过合理布置各组孔压监测点,对各组孔压的变化及超孔压力的消散周期进行了试验研究,分析了其变化规律,依据预测的累计超孔压力与埋深提出了合理的施工控制和建议,在工程应用中取得了较好的效果,为此类工程相关施工参数的确定提供了理论依据.In the fill foundation of the dynamic replacement sand pile,monitoring the change of excess pore-water pressure is very necessary in the process of the dynamic sand pile construction.According to arranging rationally the monitor point of every group pore pressure,the experimental analysis is given,the change of every group pore pressure and dissipation period and the excess pore-water pressures are studied.The change is analyzed,bringing forward rational construction controls and suggests by the forecast of total pore-water pressure and buries depths.fairly good effect in project application is achieved,providing the relevance construction theory basis for this kind of project.
