摘　　要：通过厦门环东海域综合整治项目,详细介绍抛填开山土造地强夯试验的方案,讨论强夯试验的监测方法。根据强夯引起的地面变形和孔隙水压力,研究强夯的有效加固深度;强夯前后动、静力触探曲线的对比,确定最佳的强夯施工参数和强夯地基加固效果的评价,此研究方法和结论可为类似工作提供参考和借鉴。Based on the project of Xiamen surrounding east sea area project,the method of dynamic compaction is detailed introduced in the foundation that created by filling oceanic sand.The monitoring method of experiment for dynamic compaction is discussed.Based on ground deformation and pore water pressure that induced by dynamic compaction,the effective consolidated depth of dynamic compaction is studied.The dynamic and static penetration test curves that carried out before and after the treatment of dynamic compaction are compared.The optional constructional parameter of dynamic compaction is confirmed,the consolidated effect of dynamic compaction is evaluated.Methods and conclusions of this study may provide a reference for similar engineering.
