Studies on the Effects of Raft and Piles on Behavior of Piled Raft Foundations
In the design of high-rise buildings, using piled-raft foundation (PRF) has become a popular solution to meet economic and technical requirements. A good combination of raft and pile in piled-raft foundation design is necessary. In this paper, the impact of rafts and piles on the behaviour of raft piles is analysed by finite element method, via PLAXIS 3D software. In order to investigate the effect of pile layout on the behaviour of piled-raft foundation, 10 case studies were analysed by changing the number of piles, the length of each pile, and the spacing between piles. With the initial condition that the total length of the piles is constant, when the number of piles increases, the length of each pile will decrease and vice versa. Then, to analyze the impact of raft thickness on the settlement of the pile foundation, 2 in 10 cases are selected, with each case represent one type of typical pile layout. For each pile layout, the thickness of raft is changed gradually from 1 m, 2 m, 3 m, to 5 m. Based on the results of the analysed cases, the authors proposed a suitable design to reduce the differential settlement in the piled-raft foundation.
