(54) СПОСОБ ОПРЕДЕЛЕНИЯ КОЛИЧЕСТВА НЕЗАМЕРЗШЕЙ ВОДЫ И ЛЬДА В ГОРНЫХ ПОРОДАХ(54) METHOD FOR DETERMINING THE AMOUNT OF NON-FROZEN WATER AND ICE IN MOUNTAIN BREEDS
Изобретение относитс к способам определени количества незамерзшей воды и и льда в мерзлых породах и может быть использовано при проведении мерзлотнъгх съемок, изыскательских и проектных работ в услови х вечной мерзлоты применительно к объектам гражданского и промышленного строительства.The invention relates to methods for determining the amount of unfrozen water and ice in frozen rocks and can be used during frozen surveys, exploration and design work under permafrost conditions for civil and industrial construction.
Известен способ определени количества незамерзшей воды в исследуемом материале, основанный на изменении электрических свойств материала в зависимости от температуры и влагосодержани и заключаюШ .ИЙСЯ в определении этих изменений.( коррел ции их с содержанием незамерзшей воды в. породе при данной температуре 1.The known method for determining the amount of unfrozen water in the material under study is based on a change in the electrical properties of the material depending on temperature and moisture content and consists in determining these changes (correlating them with the content of unfrozen water in the rock at a given temperature 1.
К недостаткам известного спосо ба относ тс сложность определени фазового состава влаги в дисперсных породах по калометрическим и электрическим характеристикам , а также значительные погрешности при определении количества льда калориметрическим способом в области высоких температур за счет резкого возрастани теплоемкости льда, а в области низких температур за счет вли ни температуры на теплотуThe disadvantages of the known method include the difficulty of determining the phase composition of moisture in dispersed rocks by calometric and electrical characteristics, as well as significant errors in determining the amount of ice in a calorimetric method in the high temperature region due to a sharp increase in the heat capacity of ice, and in the low temperature region due to the influence no temperature for warmth
фазового перехода первого рода и на теплоемкость компонентов, слагающих грунт.phase transition of the first kind and the heat capacity of the components that make up the soil.
Ближайшим техническим решением к изобретению вл етс способ определени количества незамерзшей воды и льда, заключаюш ,ийс в измерении суммарного влагосодержани образцов мерзлых пород весовым методом. Применение этого способа ограничиваетс , например, условием влагонасыш .енности породы. Кроме -того, при высоких отрицательных температурах и значительных содержани х незамерзшей воды этот способ становитс недостоверным, так как в этих случа х невозможно дифференцированно определить содержание влаги и льда в мерзлых породах Ш.The closest technical solution to the invention is a method for determining the amount of unfrozen water and ice, concludes in measuring the total moisture content of samples of frozen rocks by a gravimetric method. The application of this method is limited, for example, by the condition of the moisture content of the rock. In addition, at high negative temperatures and high concentrations of unfrozen water, this method becomes unreliable, since in these cases it is impossible to differentiate the moisture and ice content in frozen rocks of Sch.
Цель изобретени - повышение точности определени в области отрицательных температур .The purpose of the invention is to improve the accuracy of determination in the region of negative temperatures.
