Notes:
A faulted rock usually shows the swelling behavior because of clay minerals which consistof the fault gouges. It makes rock mass unstable and threatens the safety of structures built in rockmass. This study was aimed at clarifying characteristics of physical and mechanical properties offaulted rock materials. At first, microstructures and mineralogical composition associated withfaulting in the fault gouge zones were analyzed by using X-ray diffractometry (XRD) and SEMmicrophotographs. Physical properties of the faulted rock materials from fields were measured in thelaboratory. It is well known that the mechanical properties are sensitive to the mineralogicalassemblage and are affected by the shapes, distribution and preferred crystallographic orientation ofthe components. Material and direct shear tests were also conducted on faulted rock materials undersaturated and unsaturated conditions. The mechanical results were analyzed together with theanalyzed result of XRD and SEM
