500			_aABSTRACT Construction on a waterlogged ground has been a challenging for a geotechnical engineer. construction of buildings over waterlogged sites can be a problem due to low bearing capacity, high water table level and post-construction and consolidation settlements which may damage the buildings. The objectives of this study are to find out settlement behaviour of foundation and suggest suitable type of foundations that can sustain building loads safely. To achieve these objectives, three-dimensional coupled consolidation analyses were carried out to determine the bearing capacity of the shallow footings of sizes (1.22x 1.22 m2), (1.83x 1.83 m2. It was found that the ultimate load for the footing of sizes (1.22x l.22 m2), (1.83x l.83 m2) on waterlogged area were estimated to be 10 kN and 21 kN, respectively. The bearing capacity of the footing can be improved by filling material (i.e. pit sand) on waterlogged areas. The bearing capacities of the footing of sizes (1.22x 1.22 m2) and. (l.83x 1.83 m2) constructed on pit sand increased by eight and five times, respectively. Alternative types of the foundations in the waterlogged ground were suggested to get higher bearing capacity. The types of foundations are raft, single pile, pile group and piled raft. The ultimate load carrying capacity of single pile was computed as 300 kN, which is significantly higher than that of shallow footings. The ultimate load carrying capacity of (2x2) pile group was computed as 400 kN. The ultimate load carrying capacity of piled raft was computed as 620 kN.
