围埝是围海造陆工程中重要的组成部分。采用离心模型试验对模袋固化土作为海上围埝的技术进行研究,在室内短时间内真实地模拟实际工程情况。通过离心模型试验,分析了模袋固化土围埝填筑和吹填阶段地基的沉降、孔隙水压力变化规律和固结变形情况,并与实际工程监测结果进行了对比。试验结果表明,在正常施工条件下,地基变形以沉降为主,孔隙水压力在围埝填筑完成后半年内基本消散完毕,地基固结度达85%以上,地基整体稳定。认为模袋固化土海上围埝技术对软基适应性强,施工速度快,整体稳定性好。模型试验结果与实际工程监测结果一致。

The dam is an important part of harbor engineering.The centrifuge model test is used to analyze the geobag solidi-fied soil technology,which is an effective method to model the engineering practice at the laboratory.Through centrifuge model test,this paper analyzes the settlement,pore water pressure and consolidation deformation of the dam foundation,and compares with monitoring results of actual project.From the results,the settlements were the primary deformation of dam under normal construction conditions,the pore water pressure was dissipated when the dam was finished in a half year and the foundation consolidation degree was greater then 85 %.Therefore,it is shown the foundation is steady.The geobag solidified soil technology is suit for soft clay foundation for quick construction speed and foundation stability.The results of model test are in accord with monitoring results of actual project.
