Статья посвящена поиску методов решения задачи уплотнения слоя двухфазного грунта при компрессионном сжатии равномерно распределенной нагрузкой.</p></sec><sec><title>Методы</title><p>Методы. По расчетной модели сплошного изотропного тела с линейно-наследственной ползучестью в случае инвариантности среды и постоянства коэффициента Пуассона во времени, а также с учетом различной сопротивляемости скелета грунта при уплотнении и разуплотнении получено решение задачи уплотнения слоя двухфазного грунта при компрессионном сжатии равномерно распределенной нагрузкой. Рассмотрены частные случаи напряженно-деформированного состояния.</p></sec><sec><title>Результаты</title><p>Результаты. Анализ полученного решения показывает, что при постоянстве во времени коэффициента Пуассона среды, ползучесть не влияет на напряженное состояние, а лишь сказывается на деформации или перемещения (осадку), что соответствует ранее установленным положениям. При постоянстве коэффициента Пуассона напряженно-деформированное состояние среды можно определить и методом упругой аналогии, решая соответствующую упругомгновенную задачу. Решение уравнения для порового давления выполнено методом Фурье. По полученному аналитическому решению составлена блок-схема и программа в пакете Matlab с использованием встроенного языка программирования системы Matlab.</p></sec><sec><title>Вывод</title><p>Вывод. Для двух вариантов условий дренирования выполнен расчет функции порового давления, функции бокового распора и степени консолидации слоя с учетом и без учета ползучести; построены их поверхности распределения и графики изменения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim.The article is devoted to solving the problem of finding metodoa seal a two phase soil layer under compression compression uniformly distributed load.</p></sec><sec><title>Methods</title><p>Methods.On estimated model of a continuous isotropic body with linear and hereditary creep in case of invariance of the environment and a persistence of coefficient of Poisson in time, and also taking into account different resilience of a skeleton of soil when multiplexing and demultiplexing the decision of the task of multiplexing of a layer of two-phase soil in case of compression is received by a uniformly distributed load. Special cases of the intense deformed status are considered.</p></sec><sec><title>Results</title><p>Results.The analysis of the received decision shows that in case of a persistence in time of coefficient of Poisson of the environment, creep doesn't influence tension, and only affects deformation or relocation (settling) that corresponds to earlier set provisions. In case of a persistence of coefficient of Poisson the intense deformed status of the environment can be determined also by method of elastic analogy, solving the appropriate uprugomgnovenny problem. The solution of the equation for pore pressure is executed by Fourier method. According to the received analytical decision the flowchart and the program in Matlab packet with use of the built-in programming language of the Matlab system is made.</p></sec><sec><title>Conclusion</title><p>Conclusion. For two options of conditions of drainage calculation of function of pore pressure, function of a side raspor and level of consolidation of a layer taking into account and without creep is executed and their surfaces of distribution and a graphics of change are constructed.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>уплотнение двухфазного грунта</kwd><kwd>компрессионное сжатие</kwd><kwd>линейно-наследственная ползучесть</kwd><kwd>различная сопротивляемость скелета грунта при уплотнении и разуплотнении</kwd><kwd>сжимаемая поровая жидкость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>consolidation of two-phase soil</kwd><kwd>compression compression</kwd><kwd>linear and hereditary creep</kwd><kwd>different resilience of a skeleton of soil when multiplexing and demultiplexing</kwd><kwd>the compressed steam liquid</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">Агаханов Г.Э.
