ANALYSIS STARTS ON FIRST INDUCED SLIP FAILURE

This article briefly describes a field experiment to monitor a fully instrumented overconsolidated gault clay slope cutting in the process of failure. The work was carried out by researchers cooper, grant, petley and bromhead from Southampton and warwick universities and kingston polytechnic. It took place at selborne brick and tile company's quarry in hampshire and took two years to complete. A 3000k, 25 m wide block of clay, isolated from adjacent ground by slit trenches lined with plastic, was fed and monitored with the following equipment: 30 pneumatic piezometers, 30 vibrating wire piezometers, 20 combined recharge walls and slip indicators, inclinometers, and during the actual movement, special large movement extensometers. After the failure, the researchers found the slip plane was well marked for the forward shift by the plastic liners of the piezometers. 300 mm clay samples were taken from the line of the slip, for laboratory analysis. The failed slope was surprisingly firm, especially below the slip plane. A presentation on this project is tentatively planned for a British geotechnical society meeting in October 1988.
