Abstract:

One of the controversial issues in geotechnical engineering is the bearing capacity of shallow foundations placed on layered soil when the soil layer is overlying a rigid base; particularly when the soil layer thickness is comparable to or less than the width of the rigid foundation. The effect of the bedrock position and its shear strength properties are often not considered in conventional foundation design. A rigorous bearing capacity solution for a restricted soil layer was introduced by Farzaneh and his co-researchers. In this study the possibility of defining a modified collapse mechanism is investigated and consequently a revised collapse mechanism by extending the original model is presented. The effects of the loading parameters, such as eccentricity and inclination, and the influence of soli-substratum interface roughness on bearing capacity are presented and discussed in detail. In addition, a detailed parametric study is carried out to evaluate the effects of main variables in determining the ultimate bearing capacity of shallow foundations on restricted soil, using the proposed mechanism. Results are finally presented in design charts for practical use in geotechnical engineering.
