Discussion on the StaticDynamic Consolidation Settlement Properties of Reclaimed Soil in Offshore Area

In this study,the soil was obtained from insitu material in nearshore area of YunLin Industrial Estate.By using sea water as pore media,and using the hydraulic simulation method developed by Chien(1993) in laboratory,the packing properties of the recliamed soil is discussed.Using the traditional moist tamping method,the specimen are prepared with different relative density and fines content,and Rowetype consolidation test are conducted.The inflences of packing properties,fines content,relative density,and pore media are discussed,so that the consolidation settlement behavior are evaluated.In the study,cyclic dynamic load test are conducted by using the Rowetype consolidation cell,to evaluate the influence of earthquake or cyclic stress on recliamed soil.As shown in the results,dynamic loading has distinct influence on the consolidation settlement properties of reclaimed soil.Under 60 number of cycles,the average settlement value for dynamic consoildation settlement is 2 times larger than static consoildation settlement.The test results and the related consolidation relations can be used for land reclamation and coastal design,and research purposes.
