Моделирование деформирования железобетонной обделки тоннеля в грунте с учетом одностороннего контактного взаимодействия ее блоков

Моделирование деформирования железобетонной обделки тоннеля в грунте с учетом одностороннего контактного взаимодействия ее блоков

Abstract

In the research the problem solving methodology for deformation of constructional elements interacting between themselves and with surrounding them physically nonlinearly deformable ground is presented. Special contact finite element is described. As an illustration, the estimate of stress strain behavior for sheath of high pressure major pipeline is given.

Представлена методика решения задач деформирования элементов конструкций, взаимодействующих между собой и с окружающим их физически нелинейно-деформируемым грунтом. Описан специальный контактный конечный элемент. В качестве примера приведен расчет напряженно-деформированного состояния футляра магистрального трубопровода высокого давления.
