Introduction. Prospective transition of CIS to the European design standards in the construction industry requires development of new and modification of known engineering methods for calculation and design of construction. Creation and development of such methods should be based on fundamental research that can become the basis for the development of principally new, innovative technologies. Methods. The paper consists of basis and practical application of the method of full discretization. This method is a special modification of finite element method for the solving of problems of the creep. Practical application of the method is illustrated with modeling and applied tasks. Results. The paper presents a joint calculation of the “structure - foundation - soil” system using the example of a reservoir of a modular biological wastewater treatment plant designed for filtration fields in the village of Tasboget, Akmola region, the Republic of Kazakhstan. The full picture of the evolution of the stress-strain state of structures is gained, taking into account the material creep and the history of construction. There is a comparison of result calculations with and without technology of erection of structures.

Цели исследования. Перспективный переход СНГ на европейские стандарты проектирования в строительной отрасли требует разработки новых и модификации известных инженерных методов расчета и проектирования строительства. Создание и развитие таких методов должно основываться на фундаментальных исследованиях, которые могут стать основой для разработки принципиально новых, инновационных технологий. Методы. В статье рассматриваются основы метода полной дискретизации и его практическое применение. Этот метод является специальной модификацией метода конечных элементов для решения задач ползучести. Практическое применение метода иллюстрируется моделированием и прикладными задачами. Результаты. В работе представлен совместный расчет системы «конструкция - фундамент - грунт» на примере резервуара модульной станции биологической очистки сточных вод, проектируемой для полей фильтрации в поселке Тасбогет Акмолинской области Республики Казахстан. Во всей расчетной области получена полная картина эволюции векторов перемещений, деформаций и напряжений во времени с учетом технологии возведения, проведено сравнение результатов расчета с учетом и без учета технологии возведения конструкций.
