- Аннотация: In order to locate seepage zones in rockfill dam of Boguchan hydroelectric power plant (HPP) and to control the technical condition of rockfill dam during the filling of the reservoir electrical resistivity tomography (ERT) four monitoring cycles was carried out. For an assessment of the three-dimensional (3D) effects connected with a 3D structure of dam, and estimation of true resistivity of dam elements mathematical modelling was performed for models with changing of properties and geometry in several directions. Modelling showed that generally, geoelectric sections obtained by 2D inversion of field data don't represent true geoelectric properties of the studied object due to distortion of 2D ERT data by the 3D dam structure; significant contrast in resistivity of dam constructional elements leads to a strong distortion of geoelectric sections: the artifacts, caused by work of the inversion algorithm, occurs. The analysis of monitoring data in respect of the performed modelling allowed to exclude the presence of a seepage in the dam body.
