FIELD: measurement equipment.
SUBSTANCE: invention is related to electric survey by method of electric resistance for detection of landslip processes development sections and monitoring of filled structures. Measurements are carried out by method of vertical electric probing along bed, slope and near foot on one and another side of embankment. Capacity and specific resistance of fill material layers are identified. Longitudinal conductivity is calculated to detect sections of drowned clay material. Detected sections are used to arrange transverse geoelectric cuts. Measured relative longitudinal conductivity is detected together with slipping surface of drowned clay material. Water samples are taken on detected drowned sections, water specific electric resistance is measured to identify water mineralisation and identify relative longitudinal conductivity of clay in case of its full saturation. Comparison of measured relative longitudinal conductivity of clay to relative longitudinal conductivity in case of its full saturation helps to identify maximum possible condition for landsliding. In order to investigate dynamics of landslip processes, observations are performed in base stations located in detected drowned areas.
EFFECT: improved efficiency of detection and prediction of sections, which are hazardous from the point of view of landsliding.
