The behavior of shallow foundations resting on laterally and (or) vertically confined sand has been investigated using physical and numerical modeling. The models were designed to simulate the frequently constructed raft foundations that are surrounded by sheet-pile walls to support excavation sides of sand underlain by a rock bed. Laboratory tests were carried out utilizing a square foundation model surrounded by rigid steel walls with different depths, resting on sand that was underlain by a rough rigid layer. Varying sand-layer thicknesses and relative densities were utilized. A three-dimensional finite element analysis was conducted to verify the physical-model test results and to infer the performance of full-scale foundations. Based on the results of the experimental and numerical analyses, charts are presented to estimate the enhanced bearing capacity of square foundations resting on confined sand. These charts are presented in terms of bearing capacity of the surface foundation resting on extended sand, sand relative density, wall width to foundation width ratio, and rigid layer depth. Charts are also presented to estimate settlement reductions due to the bearing sand lateral and (or) vertical confinement.

Pile Resistance

      According to this theoretical study which was about loading of piles under different condition of loading (compression and up-lift forces ) and for deferent pile installation (vertical and inclined pile ) by which it called (positive batter pile ) when the inclination of the load and pile is in the same direction and called (negative batter pile) when the inclination of load is opposite to the pile inclination, and from studying these cases the results of analysis can be summarize in the flowing points: 1-Variation of load inclination on piles effects on the bearing capacity and uplift resistance. It was found that bearing capacity of the piles increase with increasing of load inclination up to the inclination angle (37.5ͦ) which represents the maximum bearing capacity and then the bearing capacity decrease with increasing of load inclination. 2- Variation of batter pile affects the bearing capacity of the pile and up-lift resistance. by which equivalent angle will be used as result between the load and piles inclination and this angle will be used in calculation of piles resistance . 3- It was noticed the shape of soil failure is highly affected by the inclination of pile. The shape of failure for the soil which is in contact with pile and this include (vertical and batter piles) is highly affected by the angle of inclination.
