Evaluation of horizontal stress in a landslide



The numerical modelling of landslide behaviour requires a constitutive model for the ground and the definition of an initial state of stress. This paper describes the use of various testing methods to evaluate the state of stress within a natural unstable slope. The selected site has been studied for more than fifteen years; displacements of the sliding mass, pore pressures and rainfall amount have been regularly measured. Self-boring pressuremeter tests, dilatometer tests and hydraulic fracturing tests were performed. Total pressure cells were also installed and strain controlled triaxial tests were carried out. The results are presented and discussed in this paper.
