DOI: 10.1007/s00603-020-02061-y
Abstract: For rock fractures, the degradations in the strength of contacting asperities and the surface frictional resistance are responsible for the water-induced weakening in the shear strength. To quantitatively examine their independent roles, direct shear tests… read more here.
