ABSTRACT: This article deals with the shear behavior of concrete-rock fractures under low normal stress of two dams from Quebec. These dams are located in two different geological areas. Samples from these dams were sheared under constant normal load and at the same time, laser scans of the fractures surfaces were done with a laser profilometer before and after shear test. From these data, a geostatistical study of roughness parameters has been realised. The whole study underlines some common characteristics between samples from the two dams despite the differences of substratum (limestone and granite).
