Аннотация


Анализируются результаты исследований композитной конструкции, состоящей из слоя буферного материала и жесткой сваи. Для расчета бокового давления грунта система была упрощена до схемы «подпорная стенка – буферный материал – грунт». Механизм деформации амортизирующего материала и грунта проанализирован на основе теории упругости с использованием касательного модуля в модели Дункана–Чанга в качестве модуля упругости грунта. Предполагалось, что деформационные ха-рактеристики буферных материалов соответствуют трем типичным режимам перемещения подпорной стенки: горизонтальному поступательному перемещению, вращению вокруг верхней части стенки и вращению вокруг нижней стенки. На этой основе предложены три аналитических метода расчета давления грунта за стеной. Путем сравнения результатов аналитического расчета с результатами численного моделирования подтверждена допустимость предложенных методов.
