Behavior of bearing plates resting on different types of sandy soil

Abstract EN

This Study focuses on carrying out a numerical analysis to simulate the behavior of square
thick and thin plates rested on sand soils with different densities using PLAXIS 3D program.

The selected soil density categories in this work are as following: loose, med dense and dense.

This enables to investigate the impact of soil type and density in addition to the plate
thickness on the behavior of the plate where the settlements and moments are estimated for
various stresses applied on the plate.

The plate thickness are 0.5 m and 1.30 m for thin and
thick plates respectively.

The dimensions of the studied plate are 10.0 m ×10.0 m while the
area of finite element model of soil is represented by 100.0 m × 100.0 m with depth 30.0 m.

Based on the obtained results, it can be observed that for plates resting on sand soil, thin plate
has less settlements and moments for the three type of sand soil compared with those in
thick one.

This work provides a quantitative analysis for the plate behavior resting on
different types of sand soil and it could be useful for geotechnical engineers to design safe and
economic constructions.
