Small Working

Micro-pile is a kind of small diameter bored piles, also known as root pile, pile diameter is generally 150-400mm, length-diameter ratio is generally greater than 30,and pile length is usually not more than 30m. Compared with ordinary pile, micro-pile has the advantages of fast construction speed, small working surface, high bearing capacity and small settlement.

Storey Building

Piles with raft foundation are a hybrid type of foundation in which the loads coming from the super structure is partly shared by the raft foundation and partly by the piles. A G+20 Storey building is analysed and designed in ETABS software. The modelling and analysis of piles with raft foundation is done in SAFE Software by importing the building loads. The storey drift and story displacement of the structure has been studied for the superstructure loads using response spectrum analysis and time history analysis in both X and Y axes. Then behavior of piles with Raft foundation is studied in this work by considering different parameters. The Pile diameter, Spacing of piles, Number of piles, and raft thickness are varied and keeping height of the pile as constant, the behavior of pile with raft foundation is determined. Pile with Raft foundation is economical when compared to a single pile foundation or Raft foundation. In the present work of piled with raft foundation, the load is shared between pile and raft. Hence Soil settlement is gradually reduced when the piles are introduced below the raft. Finally the optimum dimensions of pile diameter and thickness of the raft are obtained for minimum settlement.
