上覆吹填砂原料场地基强夯试验研究

Trial Dynamic Compaction Tests at a Material Docking Station Constructed by Dredged Soils

试验采用插塑料排水板+强夯的施工工艺,监测了夯坑及夯坑周边土体的沉降和隆起以及孔隙水的变化情况,分析了强夯加固范围和深度、孔隙水的消散时间以及最佳夯击次数,通过静载荷试验及双桥静力触探试验对强夯加固效果进行检验。

The trial dynamic compaction tests were conducted on a dredged ground with prefabricated vertical drains.The settlement of the craters and the ground heaves around the craters during the dynamic compaction were monitored.The effective soil improvement depth,the duration of the pore pressure dissipation as well as the optimum compaction numbers are analyzed in the paper.The results of the dynamic compaction were examined by the static plate loading tests and the cone penetration tests.
