Abstract

Изобретение относится к области геофизических измерений и может быть использовано для вертикального электрического зондирования почвенно-мерзлотного комплекса, почв, грунтов и иных минеральных образований. Техническим результатом предлагаемого устройства является обеспечение комплексности исследований при площадном обследовании почвенно-мерзлотной толщи за счет увеличения разрешающей способности и увеличения скорости измерения электрического сопротивления при малых величинах разносов питающих электродов, что позволяет определять величину электрического сопротивления на небольших интервалах глубин слоев почв и грунтов. Заявленное изобретение позволит проводить мониторинг динамики мощности пригодного для инженерно-строительных работ слоя почвенно-мерзлотного комплекса с высокой скоростью и повышенной точностью на малых глубинах (10-50 см), что важно для проведения инженерных изысканий почвенно-мерзлотного комплекса.The invention relates to the field of geophysical measurements and can be used for vertical electrical sensing of the soil-permafrost complex, soils, soils and other mineral formations. The technical result of the proposed device is to ensure the complexity of research when areal survey of soil-permafrost thickness by increasing the resolution and increasing the measurement speed of electrical resistance at small values of the spacing of the supply electrodes, which allows to determine the value of electrical resistance at small depth intervals of soil layers and soils. The claimed invention will allow to monitor the dynamics of power suitable for engineering and construction works of the soil-frozen complex with high speed and high accuracy at shallow depths (10-50 cm), which is important for carrying out engineering surveys of the soil-freezing complex.
