Relief Area

Continental-type glaciers, which covered the Montréal area, are known to have been responsible for bedrock deformation related to compressive forces. On the other hand, here we report cave systems hundreds of metres long that were caused by tension and shearing of the same bedrock. These voids were created in a low-relief area and in thin, interbedded limestone and shale. Their geometrical characteristics suggest that at least the uppermost 10 m of this limestone was broken up during middle Wisconsinan time and that this intersliding of stratified rock masses continued until the late Wisconsinan. Except for rare collapses, these voids, of unknown sizes until now, show almost no connection with the superficial geomorphology.

Primary Support

Slope excavations are often constructed in stratified host rock masses in practice. The stratification in a rock mass is generally characterised by its planar geometry and persistence. The mechanical properties of the joints dictate both the deformation and strength characteristics of the stratified rock mass. Thus, it is imperative that the influence of the joints be incorporated in any type of load-deformation analysis of slope excavations in layered rock masses. Rock bolts have been widely used as the primary support system to stabilize the rock masses of slope. In general, rock bolts reinforce rock masses through restraining the deformation within rock masses and reduces the yield region around the excavation boundary. In order to improve bolting design, it is necessary to have a good understanding of the behaviour of rock bolts in deformed rock masses. In the present paper, the numerical analysis method is adopted to built the three springs bolt element; then the excavation in the stratified rock slope is simulated to improve the understanding of the slope deformation and bolt mechanical characteristic.
