МОДЕЛЬНОЕ ИСПЫТАНИЕ И АНАЛИЗ ПРЕДЕЛЬНОЙ НЕСУЩЕЙ СПОСОБНОСТИ АНКЕРОВ В ИЛИСТОМ ГРУНТЕ A model test and the ultimate capacity analysis of multi-underreamed anchors in silty clay

Yuntao Zhou, Shengwei Shi, Qiang Cai

Аннотация


Статья посвящена исследованию работы анкеров с уширением и без них на выдергивающие нагрузки в илистых глинах. Выполнен модельный эксперимент, получены зависимости выдергивающих усилий от горизонтальных перемещений анкеров, подробно рассмотрено влияние боковой поверхности анкеров, с уширением и без, на несущую способность. Показана динамика развития деформаций в околоанкерном грунтовом пространстве, процесс образования трещин и режимы
разрушения грунта.
