Technical paper: A failed raft foundation on soft clays - investigation and analysis

By S Buttleing, Cottington Philips and L A Wood, Queen Mary College

This paper was first published in GE’s July 1982 issue

Introduction

The interaction of soils and structures has become a subject of some interest in “recent years and much of the work has been reviewed in a state of the art report by the Institution of Structural Engineers (1977).

The applicability of computational techniques to this study has given rise to programs utilising finite and boundary element techniques (Wood, 1977, 1978 and 1980) aimed at predictions of settlement, deformed shape and bending moments and taking account of the relative stiffness of soil and structural elements.

However, case studies which allow these mathematical models to be proven are rare, as detailed and reliable data on the soils, the structure, the loading and settlement history are not often available. One such case study is described hereafter.
