Soil stress distribution under loading is one of the important problems in civil engineering. Many models have been proposed to interpret the stress distribution in soil and most models assume that the soil is homogeneous and isotropic. Therefore, the actual stress distribution may be different. In addition, With the increase of the top load, soil stress does not increase linearly. In this study, vertical stress changes in sandy soil according to top load increase were measured through experiments. Experimental results, vertical soil stress due to top load increase showed an initial nonlinear behavior and when the load increases to some extent, vertical soil stress showed a linear behavior. α value obtained by existing theories always 1.00. But, α value by experiment was observed from 0.91 to 1.22 and α value was increased with increasing distance from the loading plate.
Abstract
Soil stress distribution under loading is one of the important problems in civil engineering.

In this study, vertical stress changes in sandy soil according to top load increase were measured through experiments. Experimental results, vertical soil stress due to top load increase showed an initial nonlinear behavior and when the load increases to some extent, vertical soil stress showed a linear behavior. α value obtained by existing theories always 1.00. But, α value by experiment was observed from 0.91 to 1.22 and α value was increased with increasing distance from the loading plate.
