LATERAL SWELLING PRESSURES IN ACTIVE CLAY

The additional cost of structures buried in expansive clays can be large when designed to allow for lateral swell pressures. In order to make a realistic estimate of the lateral pressures developed, a programme of field and laboratory testing was initiated for iscor on the newcastle site, where a large scale integrated steelworks was being built. Preliminary results of this investigation indicate that: (I) each clay type exhibits a unique void ratio - swell pressure relationship. (II) oedometer tests in the laboratory together with in-situ density tests on backfill clays in the field, may be used to estimate realistic lateral swell pressures. (A) /TRRL/
