ONE-DIMENSIONAL SETTLING BEHAVIOR OF A GROUP OF SOIL MATERIALS IN STATIC WATER ASSUMING COASTAL LANDFILL
There are a number of cases that coastal landfill is constructed at the port area where suburbs of the nations largest metropolitan areas and the cities are located on the alluvial plain. The seabed alluvial clay layer is, therefore, often utilized as an impervious layer for coastal landfill. Thus, it is required to prevent the degradation of impervious function of seabed clay layer by reducing the impact of poured wastes on clay layer. However, the technical data and knowledge concerning this landfill method are currently quite limited. The purpose of this study is to establish the waste pouring method which does not harm seabed. As a first step of this research, one-dimensional settling behaviour of a group of soil samples in static water has been examined using thirty centimetre diameter cylindrical container in this paper. Influential factors selected in this research are shown as follows: 1) Effect of the difference of the fluid in the cylindrical container between the tap water and the sea water. 2) Effect of the difference of grain size, amount of pouring, pouring height and the density of pouring samples on the settling behavior.
