Design Charts

It is often the case that the base of a footing rests in a foundation material consisting of more than one layer. Problems of this type have been under investigation by the authors for the last few years, and the results of these studies were reported for footings on two layers of soil and for footings on three layers of sand. This paper is an attempt to extend the authors' previous theory to cover the case of footings resting on a subsoil consisting of a dense layer of sand overlying a soft clay deposit. The results of this analysis are presented in the form of design charts.

Ultimate Moment

The ultimate bearing capacity of flexible single model piles and small pile groups of timber and nylon in loose sand and soft clay has been determined under various combinations of eccentricity and inclination of the load varying in direction from vertical to horizontal. The results of the load tests are presented in the form of polar bearing capacity diagrams and they are compared with the theoretical estimates based on the concept of an effective embedment depth in terms of the behaviour of equivalent rigid piles. Reasonable agreement has been found between the observed and predicted ultimate bearing capacity of flexible piles under any combination of eccentricity and inclination of loads. Key words: flexible piles, pile groups, ultimate bearing capacity, ultimate moment, model test, eccentric load, inclined load, sand, clay.

Strip Footings

The ultimate bearing capacity of footings resting on subsoils consisting of two layers has been investigated for the cases of dense sand on soft clay and loose sand on stiff clay. The analyses of different modes of soil failure are compared with the results of model tests on circular and strip footings and some field observations of foundation failures.
