TREATMENT AND SUBSEQUENT PERFORMANCE OF COHESIVE FILL LEFT BY OPENCAST IRONSTONE MINING AT SNATCHILL EXPERIMENTAL HOUSING SITE, CORBY

A carefully monitored experiment is being carried out involving the treatment of backfilled land left by opencast ironstone mining and the subsequent erection of groups of houses on the treated ground. The overburden at the site had been excavated by dragline during the mining operation and the resulting backfill was loose, unsaturated and about 24 M deep, the upper part being predominantly cohesive. Each of three areas of the site was subjected to a different form of ground treatment and subsequently groups of two-storey dwellings of standard design with trench fill foundations have been built on each of these areas and on a fourth control area of untreated ground. The three types of ground treatment used were pre-loading with a surcharge of fill, "dynamic consolidation" and inundation. Borehole settlement gauges of the magnet extensometer type were installed prior to ground treatment to monitor the compression produced at different depths within the soil. (TRRL)
