摘　　要：吹填造陆已成为沿海地区解决土地匮乏的有效方法。为使吹填土迅速排水固结以缩短工期,以浙江省舟山市某项目为研究对象,采用堆载预压法对场地进行地基处理。通过对地基处理前、后的场地进行岩土工程勘察,研究吹填成陆工程浅部黏性土的变化规律。结果表明,浅部黏性土层的物理性质指标(含水量、孔隙比、饱和度、液性指数)有一定的改善,力学性质指标(压缩系数、黏聚力、内摩擦角)得到增强。Dredger fill making lands is an effective way to solve the land shortage in coastal areas.In order to quicken drainage consolidition and shorten the construction period of dredger fill,taken the dredger fill in coast region of Zhoushan City,Zhejiang Province as studied object,adopt the load pre-pressure method for ground treatment of the site.The change law of clay in Zhoushan were studied by geotechnical investigation before and after ground treatment.The results showed that the physical property index of clay(water content,void ratio,saturation,liquid index)has been some improvement,the mechanical property index of clay(coefficient of compressibility,cohesion force,friction angle)has been enhanced.
