ФИЗИЧЕСКОЕ МОДЕЛИРОВАНИЕ ПОВЕДЕНИЯ САМОРАСШИРЯЮЩИХСЯ СТАЛЬНЫХ СВАЙ Experimental and comparative investigations of a new self-expanded steel pile behaviour via physical modelling (FCV-AUT)

Аннотация


Рассматриваются новые конструкции саморасширяющихся свай – «пузырчатая» (bubble pile) и «крылатая» (wing pile). Эти сваи были исследованы в песчаных грунтах различной плотности с помощью устройства, разработанного в Амиркабирском технологическом университете. Для сравнения их поведения и несущей способности с традиционными сваями было проведено 32 испытания
на статическую нагрузку при растяжении и сжатии. Результаты испытаний показали, что новые сваи могут противостоять значительным растягивающим и сжимающим нагрузкам и могут быть возможной альтернативой традиционным сваям.
