ПРЕДЕЛЬНАЯ НЕСУЩАЯ СПОСОБНОСТЬ НА ВЫДЕРГИВАНИЕ АНКЕРОВ С ПЕРЕМЕННЫМ ДИАМЕТРОМ В СЛАБОМ ГРУНТЕ Ultimate uplift capacity for multi-underreamed anchors in soft soil

Yuntao Zhou, Jiong Liang, Shengwei Shi, Qiang Cai

Аннотация


Исследуется влияние на предельную несущую способность на выдергивание анкеров с переменным диаметром параметров самого анкера, окружающего грунта, и поверхности раздела анкер – грунт. В рамках теории предельного равновесия используются модели с поверхностью разрушения арочного и цилиндрического типов. Предложенная методика находится в тесном соответствии с данными модельных испытаний. Из-за взаимного влияния усилий бокового и торцевого сопротивлений предельная несущая способность анкеров с переменным диаметром выше, чем у анкеров классического типа.
