The use of ERT for investigation of berzhita landslide, tirana area, albania

Abstract

In this paper we present an engineering geological-geophysical investigation of the Berzhita landslide, Tirana area, Albania. The work includes engineering-geological field investigation and geophysical measurements. A detailed field investigation was conducted to delineate the aerial extent and a general direction of movement of the landslide zone, assess lithological section, estimate the thickness of the sliding layer, and delineate water saturated zones. In order to study in detail this landslide, two perpendicular Electrical Resistance Tomography (ERT) profiles were carried out. A detailed engineering-geological study was conducted including, engineering mapping on scale 1:100, geotechnical investigations such as drilling and trial pits at 14 points with depths 3-4 m, soil sampling and laboratory tests for geotechnical parameter studies. The results of field investigations are presented as engineering geological map and several geological and resistivity images cross-sections which clarify the geometry and subsurface characteristics of the landslide. © Springer-Verlag Berlin Heidelberg 2013.
