Abstract: Pile-raft foundation is a modern approach in place of conservative method for multi-storey buildings or in some special circumstances. In pile-raft analysis the load settlement behaviour of pile foundation, raft foundation and combination of pile-raft foundation is determined. The use of combination of pile-raft is basically a new technique for economy of foundation resting on the sand. Model Study is carried out to determine the suitability of the pile raft foundation for sand. In this modal study we have studied load deflection behavior of pile-raft foundation by making a prototype of a footing and applying a static load in each case and settlement of footing is noted in 2 dial gauges fixed at alternate edges of footing. As an observation the settlement behaviour of pile-raft foundation is being found less as compared to other two types of foundations tested. The pile-raft foundation is very important and helpful for everyone because if we have soil of low bearing capacity then stabilization of soil is need to be done using different material but the use of pile-raft in sand can eliminate this kind of expenses occurs during construction.
