The results obtained from a controlled field trial of strip foundations on a heterogeneous fill reinforced with stone columns are presented. Comparison is made with the performance of an identical foundation on the virgin fill and with results from numerical models. Comprehensive site investigation data are given, together with measured settlements, bearing pressures, and bending strains. It is concluded that the stone columns improved the performance of the strip foundation, although measured stress ratios were lower than computed values. Bending moments, deduced from the measured strains, suggest that hogging moments are unlikely to occur for a strip foundation on stone columns with a thickness of at least 400mm.

Excursus. Redressing the Balance in Higher Education: a Major Opportunity for Sir Ron Dearing's Inqu
Dr James H. Armstrong, whose services to engineering and education were recognised by the award of an OBE in the New Year Honours, retired from the BDP partnership in 1989. Since then he has become an increasingly influential figure in the realm of engineering education. He is Chairman of the Higher Education Foundation and, as a Fellow of the Royal Academy of Engineering and member of its Education Committee, he has played a key role in setting up the Visiting Professors Group, now around 140 strong.
