        <p>This article presents the spatial computational scheme, the mathematical model, the calculation method and the algorithm for solving problems of assessing the stress-strain state (SSS) of the Jidalisoy earth dams, which have complex geometric parameters, under the action of their own weight and the hydrostatic pressure of water, on the basis of the Lagrange-d‘Alembert variational principle. Using the universal Abaqus software, numerical calculations were carried out to study the spatial stress-strain state of an earth dam taking into account the structural features of the facility, and the results are presented. On the basis of the results obtained it is shown that the study of the SSS of the Jidalisoy earth dam with complex geometric parameters under static loads must be carried out only by means of spatial models of the structure.</p>

        <p>В статье представлены пространственная расчетная схема, математическая модель, метод расчета и алгоритм решения задач по оценке напряженно-деформированного состояния (НДС) земляных плотин Жидалисой со сложными геометрическими параметрами на основе вариационного принципа Лагранжа-Далембера под воздействием удельного веса и гидростатического давления воды. С использованием универсальной программы Abaqus выполнены численные расчеты по исследованию пространственного напряженно-деформированного состояния земляной плотины с учетом конструктивных особенностей сооружения и представлены результаты. На основании полученных результатов показано, что исследование КДХ Жидалисойской земляной плотины под действием статических нагрузок, имеющей сложные геометрические параметры, следует проводить с использованием только пространственных моделей сооружения.</p>

Abaqus universal dasturidan foydalanib, inshootning konstruktiv xususiyatlarini hisobga olgan holda, gruntli to‘g‘onning fazoviy kuchlanish-deformatsiya holatini o‘rganish uchun raqamli hisob ishlari bajarilib, natijalari taqdim etilgan. Olingan natijalar asosida murakkab geometrik parametrlarga ega bo‘lgan Jidalisoy gruntli to‘g‘onining statik yuklamalar ta‘siridagi KDHni o‘rganish - faqat inshootning fazoviy modellari yordamida hisob ishlarini amalga oshirish kerakligi ko‘rsatib berilgan.</p>
