Дан краткий анализ методов очистки от нефтезагрязнений в основаниях строящихся и эксплуатируемых зданий и сооружений. Рассмотрена возможность очистки грунтов электрохимическим методом с использованием системы оперативного геофизического мониторинга в натурных условиях. Описаны методика проведения натурных испытаний метода контролируемой электрохимической очистки грунта от нефтезагрязнений и экспериментальная установка. Изложены результаты инженерно-геологических изысканий грунтового массива, искусственно насыщенного нефтепродуктами (отработанным маслом, бензином). Детализированы процессы образования зон осушения, скопления нефтепродуктов при электроосмотическом переносе, изменения структуры грунта в результате фазового преобразования и растворения нефтепродуктов. Установлено явление коагуляции нефтепродуктов в порах грунта при электрообработке, приводящее к увеличению крупности песчаных и глинистых компонентов и грунта, способствующее его дезактивации. Экспериментально доказана эффективность электрохимической очистки малопроницаемых песчано-глинистых грунтов.

The paper presents a brief analysis of methods of foundation soil purification from oil products. A method of electrochemical soil purification is suggested using the system of operational geophysical monitoring in natural conditions. A full-scale test method of controlled electrochemical soil purification and the experimental setup are described. The results of engineering-geological surveys of the soil massif artificially saturated with oil products (waste oil, gasoline) are presented. The formation of drainage zones, accumulation of petroleum products during electroosmotic transfer, soil structure changes caused by the phase transformation and dissolution of petroleum products are presented. the phenomenon of coagulation of oil products in soil during the electrical processing leading to the increase in the particle size in sand and clay components due to changes in the electrical soil resistance. The experiments prove the efficiency of electrochemical cleaning of low-permeable sandy-clay soils.
