study of a landslide using 1d and 2d resistivity surveys in northern iran-rudbar region
نویسندگان
چکیده
we use high-resolution electrical resistivity imaging to delineate the geometry of the landslide and discontinuity surface between slide mass and bedrock in roudbar region, ghazvin-rasht-anzali railway (the tunnel no. 2 at km. 108+825). the roudbar region characterized by high geological hazard and shows a complete panorama of mass movements. in this area, different landslide types predisposed and tightly controlled by the geostructural characteristics. geoelectrical images are produced from dipole-dipole, schlumberger and combined resistivity profiling data along arrays spanning selected profiles positioned perpendicular and parallel to the tunnel route in landslide area. regarding the surface geology, geomorphology, integration and comparison of dipole-dipole results with other geophysical data delineated the geometry and characteristics of the landslide and geological structures.
