Abstract:
In order to solve a number of engineering and hydrogeological problems, it is important to discern between the investigated incision horizons (layers) that are aquiferous or with shifting landslide surface. In geophysics, the method of vertical electrical sounding is the most commonly employed to solve such problems. However, the practical solution of problem becomes difficult or impossible if the horizons sought are low-powered or located in considerable depths. It is shown that in engineering-hydrogeological conditions of the Armenian Volcanic Highland type of territory it is effective to use the well-known multi-electrode sounding by the method of subtraction of fields (SMSF). However, its practical application requires examination of the features of the distribution of the electric field of multipoint grounding electrodes and determining the way of quantitative processing of the observed graphs. The examples given show the effectiveness of the proposed methodology in the solution of targeted engineering hydrogeological problems.
