Abstract
This paper presents a series of physical tests used to model cylindrical shafts in order to study the earth pressure distribution and the induced vertical and horizontal displacements of the adjacent soil. Various methods used to model cylindrical shafts are described: one or more semi-circular aluminium tubes, curved steel segments cut longitudinally or a latex bag filled with a heavy fluid. The results showed that the lateral earth pressure distribution is well correlated with the results based on Terzaghi’s and Berezantzev’s theories. Also, the lateral earth pressure decreases until the active wall displacement is occurred. Based on the physical tests, researchers developed a series of equations that can be used to calculate the vertical and horizontal displacements of the soil.
