COMPARISON BETWEEN PILE AND COMBINED PILED RAFT FOUNDATION

Abstract

The important question related to the design of high-rise buildings on the settlement-sensitive soil (clays) is the cost-optimised reduction of settlements to minimise possible damage and to reduce deformations of high-rise building. An old method for reducing settlement of foundation where the presence of loose soil and high depth of water table co-exists is to construct a pile foundation on a hard layer. In the case of a deep stiff seated layer, a pile foundation is connected to a large amount of long and large diameter piles which results in huge construction costs.
