EARTH PRESSURE OBSERVATIONS ON A RETAINING WALL IN EXPANSIVE CLAY, GOUGER STREET MAIL EXCHANGE, ADELAIDE

A section of a basement retaining wall in Adelaide, 25m long and 7.5m high, has been extensively instrumented. The basement is located in a moisture-sensitive expansive clay subjected to changes in the moisture environment. The instrumentation comprises twenty-four earth pressure cells at the wall/clay interface and thrity-one psychrometers in the clay mass behind the wall. Earth pressures are being measured, together with changes in the moisture environment, for comparison with current design assumptions, and with predictions from more advanced method of modelling the interacting retaining wall.clay system. The instrument installation was accompanied by a comprehensive sampling and laboratory testing program, designed to measure material properties relevant to available models of material behaviour. The results of the laboratory testing and the field observations for the first two years are presented and discussed. /Author/
