摘要
吹填砂是沿海陆域整治的重要载体。由于其特殊的工程性质,为工程建设的需要,必须对其进行处理。针对厦门环东海域整治,对由吹填形成的砾砂类填料,开展强夯试验研究,进行了孔隙水压力监测、单点夯试验;同时采用载荷试验、重型动力触探、标准贯入、瑞利波测试等检测效果,分析得出了用于指导滨海吹填砂地基的处理方法及合理的施工参数,在工程中实际应用并取得了成功。
Hydraulic fill sand is the main materials for ground improvement along coastal areas.Because of its special engineering characteristics,it must be treated before application.For the project alongside eastern coastal region of Xiamen,dynamic consolidation was carried out for the hydraulic fill sand ground treatment.The pore-water pressure was monitored during the compaction tests.Reasonable construction parameters and treatment measures were provided through the dynamic compaction tests.Different test methods,such as loading tests,heavy dynamic penetration tests,and SPT were applied with to testify the consolidation results.
