Применить методы математического моделирования процесса растворения и выноса солей при фильтрации в трещиноватых загипсованных породах. Поскольку увеличение раскрытия трещин за счет растворения их стенок происходит при движении воды по трещинам пород, содержащих растворимые включения, то за счет изменения пористости и трещиноватости пород увеличиваются фильтрационные расходы и скорость фильтрации, что может привести к просадкам оснований. Метод. Рассмотрен процесс для наиболее простой схемы одиночной заполненной дисперсным материалом трещины длиной l и шириной 2h; скорость фильтрации считается постоянной и равной v. Для решения полученного параболического уравнения используется экономичная разностная схема переменных направлений (продольно-поперечная схема), которая является абсолютно устойчивой и требует на каждом временном шаге решения системы линейных алгебраических уравнений (СЛАУ) с трехдиагональной матрицей. Результат. Пpивeдeн алгоритм, cocтaвлeнa и oтлaжeнa пpoгpaммa для расчета pacпpeдeлeния кoнцeнтpaций пo тpeщинe в среде DELFI. Обобщены численные результаты pacчeтa pacпpeдeлeний кoнцeнтpaций pacтвopa в зaпoлнeннoй тpeщинe. Вывод. Наряду с известными методами, пpивeдeнный алгоритм может быть использован при моделировании процесса растворения и выноса солей при фильтрации в трещиноватых породах. </p></abstract><trans-abstract xml:lang="en"><p>Objectives. A mathematical modeling method is used to describe the process of resorption and salt depletion by filtration through fractured gypsified rock strata.Since the increase in the opening of crevasses due to resorption of their walls from water percolating through rock fractures containing soluble contaminants, a change in the porosity and fracturing of rocks increases filtration rate and Darcy flux leading to foundation subsidence. Method. A process for the simplest schema with a single particulate material filling a fissure of length l and width 2h is examined; the filtration rate is considered constant and equal to v. To solve the resulting parabolic equation the economical difference scheme of alternating directions (convergence formula) is used; this is totally stable and requires simultaneous linear algebraic equations (SLAE) equations with a tridiagonal matrix at each stage of the solution. Results. An algorithm, compiled and programmed to calculate the distribution of concentrations in the fissure using DELPHI programming language, is proposed. Numerical results are summarised due to dissolution concentration distinction in the filled fissure. Conclusion. Using a modified algorithm, the compiled and debugged program using DELPHI programming language allows the distribution of concentrations to be calculated. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>фильтрация</kwd><kwd>трещина</kwd><kwd>диффузия</kwd><kwd>математическая модель</kwd><kwd>расчетная схема</kwd><kwd>устойчивость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>filtering</kwd><kwd>fissure</kwd><kwd>diffusion</kwd><kwd>mathematical model</kwd><kwd>formula</kwd><kwd>stability</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Баламирзоев А.Г.
