ResumoOne year after the construction of a hospital in Saint-Jérôme, Lac Saint-Jean, a slide occurred in the slope behind the hospital building; that first slide was followed by three other small slides which took place during the following wet seasons. Some remedial works were carried out in order to drain the debris and decrease the pore pressures at the toe and behind the clay face by means of perforated drain pipes and drainage trenches, and to channel the runoff water from the plateau down into the river. The present paper gives a discussion on the causes and the mechanism of the slides, a description of the corrective works carried out, and an evaluation of their effectiveness based on different visual observations, on pore pressure and shear strength measurements, and on stability analysis.
