  • Bearing Capacity of strip footings near slopes
    Geotechnical and Geological Engineering, 2010
    Co-Authors: Francesco Castelli, Ernesto Motta

    Abstract:

    In the last decades a great attention was given by many authors to the evaluation of the static and seismic Bearing Capacity of footings near slopes. In this paper a model has been developed based on the limit equilibrium method, considering a circular surface propagates towards the slope until the sloping ground is reached. The Bearing Capacity is investigated considering either the distance of the footing from the edge of the slope and/or the effect of the footing embedment. A validation of the proposed model was made by a comparison with solutions taken from literature regarding the evaluation of the Bearing Capacity for a footing adjacent to a slope and for an inclined load. The loading conditions consist in vertical and horizontal stress on the footing and on the soil below the footing. Both the inertial and kinematic effects of the seismic loading have been analyzed, and a simple equation has been derived for the evaluation of the seismic Bearing Capacity. The static and seismic Bearing Capacity has been investigated as a function of the soil friction angle, of the seismic coefficient, of the sloping ground. Finally, the influence of the distance of the footing from the edge of the slope was taken into consideration in the evaluation of the Bearing Capacity, and a threshold distance at which the reduction of the Bearing Capacity due to the sloping ground vanishes has been defined.

  • Evaluation of the Bearing Capacity of footings on slopes
    International Journal of Physical Modelling in Geotechnics, 2012
    Co-Authors: Francesco Castelli, Valentina Lentini

    Abstract:

    In the last few decades, a great amount of interest has developed in the evaluation of the influence of Bearing Capacity of shallow foundations on slopes. When a footing is placed near a slope the Bearing Capacity may be reduced. In fact, the failure mechanism is influenced by the distance of the foundation from the edge of the sloping ground. In order to investigate the effect of the Bearing Capacity of shallow foundations on slopes, model footing tests were performed. This paper presents the results of the investigation, to establish both qualitative and quantitative relationships between the ultimate load of the soil–foundation system and the location of the footing with respect to the slope. Values of ultimate loads deduced from experimental tests are compared with values derived by a numerical analysis based on the limit equilibrium method. Modified Bearing Capacity factors which take into account the effect of the sloping ground are proposed.

  • Bearing Capacity Computation
    Geotechnical Engineering Calculations and Rules of Thumb, 2020
    Co-Authors: Ruwan Rajapakse

    Abstract:

    This chapter discusses the Bearing Capacity equations developed by Terzaghi, which are used in order to compute the Bearing Capacity of foundations. It explains the three properties of soil that develop its Bearing Capacity. It describes the terms used in the Terzaghi Bearing Capacity equation, the ultimate Bearing Capacity, the cohesion term, the surcharge term, and the density term. Each term in the Terzaghi Bearing Capacity equation impacts the Bearing Capacity of a footing. It concerns the computation of Bearing Capacity in sandy soil and explores a wall footing in a homogeneous sand layer and a column footing in a homogeneous clay layer. The Bearing Capacity and column footing in soil layered with clay and sand is described. Furthermore, it explores a column footing on layered soil with two sand layers. It also covers a wall footing in soil with two different layers of clay and considers a strip footing design in sand using SPT (N) values, for the no groundwater case. It then discusses the Bearing Capacity when groundwater is present and when groundwater is above and below the bottom of footing level. Finally, it discusses shallow foundations in bridge abutments.
