Abstract

Изобретение относится к области геофизических исследований мерзлых грунтов и может быть использовано для определения мощности пригодного для инженерно-строительных работ почвенно-мерзлотного комплекса, а также для изучения грунтов криолитозоны. Сущность изобретения заключается в вертикальном электрическом зондировании почвенно-мерзлотной толщи с интервалом питающих электродов, равным 5-20 см, и предварительном продольном электрическом зондировании с интервалом 20-60 см для выбора исследуемых участков с однородной растительностью. По графикам удельного электрического сопротивления определяют нижнюю границу пригодного для инженерно-строительных работ почвенно-мерзлотного комплекса. Предложенный способ отличается от большинства существующих способов тем, что позволяет обеспечивать измерение мощности слоя почвенно-мерзлотного комплекса, пригодного для инженерно-строительных работ, без механического нарушения целостности почвенно-растительного покрова. Отсутствие необходимости заложения шурфов, бурения или механического проникновения в почвенно-мерзлотную толщу при помощи стального щупа существенно удешевляет и упрощает инженерно-строительные изыскания в мерзлых грунтах. Заявленное изобретение позволит проводить мониторинг динамики мощности пригодного для инженерно-строительных работ слоя почвенно-мерзлотного комплекса с высокой скоростью и без проникновения в почвенно-грунтовую массу.The invention relates to the field of geophysical studies of frozen soils and can be used to determine the power suitable for engineering and construction work of the soil-frozen complex, as well as to study the soils of the cryolithozone. The invention consists in vertical electrical sounding of soil-permafrost thickness with an interval of supply electrodes equal to 5-20 cm, and preliminary longitudinal electrical sounding with an interval of 20-60 cm to select the studied areas with uniform vegetation. According to the graphs of electrical resistivity determine the lower limit of soil-permafrost complex suitable for engineering and construction work. The proposed method differs from most of the existing methods in that it allows the measurement of the thickness of the soil-permafrost complex, suitable for engineering and construction works, without mechanical violation of the integrity of the land cover. The absence of the necessity of laying holes, drilling, or mechanical penetration into the soil-permafrost thickness using a steel probe significantly reduces the cost and simplifies engineering and construction surveys in frozen 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 without penetration into the soil-ground mass.
