Представлена методика определения механических характеристик вязкоупругого грунта. Из экспериментальных данных испытания образца на ползучесть получена функция ползучести грунта. Далее численно-аналитическим методом ломаных определена функция релаксации грунта. Представление функции ползучести в виде ломаной линии позволило получить функцию релаксации (обратную функцию к функции ползучести в изображениях по Лапласу – Карсону) как решение задачи вязкоупругости. На основании известного изображения искомого оригинала функции релаксации в виде ломаной линии осуществлен переход от изображения к оригиналу по методу ломаных, который сведен к системе линейных алгебраических уравнений относительно искомых параметров функции релаксации. Для определения функции релаксации по данной методике нет необходимости ставить эксперимент с образцом грунта на релаксацию, что позволяет экономить на проведении лабораторного эксперимента. Предложенный алгоритм представляет интерес при проектировании объектов строительства на слабых грунтовых основаниях с учетом вязкоупругих свойств грунта. </p></abstract><trans-abstract xml:lang="en"><p>Experimental studies of processes in soil foundations under load show that soils exhibit viscoelastic properties. The article presents the method for determining the mechanical characteristics of viscoelastic soil. One of the functions, for example, the soil creep function, is obtained from the experimental data of testing a sample for creep. Next, the soil relaxation function was determined using the numerical-analytical method of broken lines. The representation of the creep function in the form of a broken line made it possible to obtain the relaxation function (the inverse function to the creep function in Laplace – Carson images) as a solution of the viscoelasticity problem. Based on the known image of the desired original of the relaxation function in the form of a broken line, a transition from the image to the original was made using the broken line method, which is reduced to a system of linear algebraic equations regarding the desired parameters of the relaxation function. To determine the relaxation function using the proposed method, there is no need to experiment with a soil sample for relaxation. This saves on laboratory experiments. The proposed algorithm is of interest when designing construction projects on weak soil foundations, taking into account the viscoelastic properties of the soil.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вязкоупругие свойства грунта</kwd><kwd>грунтовое основание</kwd><kwd>функции ползучести и релаксации</kwd><kwd>метод ломаных</kwd></kwd-group><kwd-group xml:lang="en"><kwd>viscoelastic properties of soil</kwd><kwd>soil foundation</kwd><kwd>creep and relaxation functions</kwd><kwd>broken line method</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">Nguyen, P.
