Abstract
This article treats experience feedback of the behavior of six tanks founded on layered soft ground reinforced by rigid inclusion “RI” columns of floating “INSER” in the plain of Mitidja, Boufarik, Algeria. The rigid inclusions columns have a diameter 0.42 m and 26.3 m to 28.3 m length, uniformly distributed according to a grid of 1.8 × 1.8 m2. The load transfer mattress would was 2.30 m in thickness and consist of densely rolled granular material with geogrid depending on spacing of the stiff columns. After the Achievements of the realization of the works a loading is carried out on the latter. Settlements appeared exceed even settlements acceptable of work “15 cm” by thus compromising the project. The instrumentation implemented allowed the follow-up uninterrupted settlements according to the evolution of the stresses under the foundation rafts. Numerical calculations by finite elements and analytical methods were carried out and the results obtained are compared with measurements.
