TECHNIQUE FOR RAISING THE BEARING CLAYS FORMING THE SUBSTRUCTURE FOR RAILROAD TRACKS IN A SURFACE MINE

FAEHIGKEIT DER TONE IM UNTERBAU VON STATIONAEREN BAHNGLEISEN IN TAGEBAUEN

The tracks at the Trojanowo surface mine in Bulgaria are laid on clay strata that, within about 6 mo. , reach a moisture content of 60 to 65%, causing a decrease in static bearing capacity below 1 kg/sq. cm. The electro-chemical consolidation technique that is described in the paper attacks two weak points in the dispersed (clay plus water) system, namely: contacts between the surface of solids and water and the density of water strata; as well as the contacts between the particles of the solid phase by creating coagulation and then crystallization nuclei. Increases of the bearing capacity of up to 400% by the treatment have been achieved.
