BEHAVIOR OF RAFT ON FULL AND PARTIAL DISPLACEMENT PILES

Abstract

The piled •raft fmmdations are now widely used in many Leas of the I world. The main advantages of such a foundation type are: I I a) Reduction in maximum and differential settlements of thd. designe•d

foundation and eventually of the movements of existink close-by foundations. i\ b) Reduction in foundation tilting either due to load eccentricity, or due to I

irregularities of strata thicknesses or due to variations of the pr<i>perties of the involved soils. I

c) Prevention of settlement joints between differently loaded pahs of the I building.

d) Increase In the global bearing capacity of the foundation. \

e) Increase in the foundation resistance against horizontal loading and I overturning moments. I I f) Reduction in the likelihood of damage to structural components and

sensitive architectural finishes due to the increase of initial conshlidation I settlement of elements. I I g) Decrease in internal raft stresses and moments by choosing optirhal pile . . I pos1t1on.
