A CONTRIBUTION TO THE ANALYSIS OF THE STANSTEAD ABBOTTS EMBANKMENT ---PROCEEDINGS OF THE PREDICTION SYMPOSIUM ON A REINFORCED EMBANKMENT ON SOFT GROUND, 17-18 SEPTEMBER 1986, KING'S COLLEGE, DEPT OF CIVIL ENGINEERING, LONDON

This paper summarizes the information available to contestants to enable them to predict the behaviour of the stanstead abbotts trial embankment. It also enumerates important missing information, notably the lack of information on (a) the undrained behaviour of the embankment fill; and (b) the compaction procedures used in constructing the embankment in the field. Because assumptions were required to supplement this missing information extensive analyses of the embankment were considered inappropriate. Conventional consolidation settlement analyses, limit equilibrium analyses and the results of previous finite element studies were used as a basis for predicting the behaviour of the embankment. Predictions were provided for the following: (1) at the end of construction: (a) the maximum load in the reinforcement and its distribution; (B) the horizontal displacement at point d in the upper clay, below the reinforcement; (c) the displacements in the upper clay across the section; (d) pore water pressure change at points b and c during construction; (e) the deformed shape of inclinometer 1; (f) the safety factor; and (2) after 18 months of consolidation: (a) the maximum load in the tensar SR-2 and the distribution of load across the section; (a) the maximum settlement at position a; and (c) the factor of safety. For the covering abstract of the conference see IRRD 819605.
