Abstract
Most man-made, onshore earth structures are constructed by compaction. Optimum compaction can increase strength and decrease compressibility and permeability. However, the compaction mechanism remains to be defined in soil mechanics and there is no alternative but to apply empirical methods at the geotechnical engineering site. In this study, compaction is assumed as compression of unsaturated soil under water-undrained and air-drained conditions, and the compaction simulation is conducted with soil/water /air coupled finite element analysis. Consequently, the shape of the compaction curve can be drawn on the coordinates of water content and dry density. Moreover, direct shear simulation of the specimen obtained from compaction simulation was also conducted.
