АКТИВНОЕ ДАВЛЕНИЕ ГРУНТА НА КАРКАСНО-АНКЕРНЫЕ КОНСТРУКЦИИ С УЧЕТОМ ПРЕДВАРИТЕЛЬНЫХ НАПРЯЖЕНИЙ Analysis of Active Earth Pressure on Anchored-Frame Structures Considering Prestresses

Аннотация


Рассматривается влияние предварительных напряжений, создаваемых анкерами, при укреплении откосов грунта подпорными анкерно-каркасными конструкциями. Предложен метод учета влияния предварительных напряжений на активное давление грунта на подпорную стенку. Исследуется влияние расстояния между анкерами, а также прочностных характеристик грунта. С использованием аналитического и конечно-элементного подходов выполнено сравнение предложенного метода расчета с
известными (методом Ренкина и нормативным). Показано, что неучёт предварительных напряжений может привести к катастрофическим последствиям.
