Investigation of Physical Model on Soft Soil Reinforced by Rigid Inclusions Under Cyclic Loading

Three-Dimensional Physical Modeling on Soft Soil Improvement by Rigid Inclusions

“…Although this smallscale model did not respect the real scale structure, the experiments will aid in optimizing the design of inclusion systems, and determining the most effective parameters for achieving the load transfer mechanism and settlement control. [12][13][14] and Insoog et al [15], this model is under the normal gravity at 1/10th scale on the lengths. The model is made of a steel tank of 1x1 m 2 , containing 16 steel pipes with a diameter of 40 mm and a height of 600 mm.…”

“…For investigating the load transfer mechanism in the laboratory, several materials were used to represent real soft soil (e.g., foam cushion [3][4], polyurethane foam (PU) [7], a mixture of fine sand, polystyrene balls, and water, [12][13][14][15]). To facilitate the sample preparation, the compressible soil used in this study was made of a mixture of polystyrene balls, sand, and water ( [15]). A mixture of sand: water: polystyrene balls at 40: 4: 1 by weight was prepared and installed in the steel tank with the density of 4.5 kN/m 3 .…”

“…Fig.1aand 1b show the small-scale physical model in this study. Based on the experimental observations performed by Houda et al[12][13][14] and Insoog et al[15], this model is under the normal gravity at 1/10th scale on the lengths. The model is made of a steel tank of 1x1 m 2 , containing 16 steel pipes with a diameter of 40 mm and a height of 600 mm.…”
