THE BEHAVIOUR OF A REINFORCED TRIAL EMBANKMENT ON SOFT SHALLOW FOUNDATIONS ---PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM ON THEORY AND PRACTICE OF EARTH REINFORCEMENT, FUKUOKA, KYUSHU, JAPAN, 5-7 OCTOBER 1988

This paper described the behaviour of a fully instrumented trial embankment designed to test the behaviour of a reinforced earth embankment constructed across soft alluvial deposits on the stanstead abbotts bypass. Fifteen load cells and 2 pairs of bison strain measuring devices were installed in the tensar SR 2 grid. The load cells were installed in sets of 3 at 5 locations. Pore water pressure, its distribution and its decay were measured with the resulting settlement. Key instrumentation included inclinometers, hydraulic and pneumatic piezometers, and a horizontal profile gauge. A comparison of load and strain in the reinforcement and in the soil was made. The analytical approaches adopted were of two types: (a) conventional classical solutions based on either: (a) stress field solutions or on variations in the slip cycle analysis; and (b) numerical models. Various predictions were based on finite element methods, some incorporating simple elastic formulations while others used highly developed elastic/plastic criteria. Post construction data obtained from the main embankment were also provided. The key findings derived from the data and the insights gained from them were discussed. For the covering abstract of the symposium see IRRD 818063.
