Abstract:
|
The behaviour of an instrumented unstable
slope in a profile of weathered overconsolidated clay has
been analysed. Available field investigation data and laboratory
tests were integrated in a coupled hydromechanical
model of the slope. Particular attention was given to
the unsaturated soil conditions above the water table and
to the influence of the rainfall record. Recorded pore-water
pressures helped to identify the hydrogeological conditions
of the slope. The coupled model was used to
compute slope deformations and the variation of safety
with time. Actual rainfall records were also integrated
into the analysis. Comparison of measurements and calculations
illustrate the nature of the slope instability and
the complex relationships between mechanical and hydraulic
factors. |
