Abstract

The lateral earth pressure of vertical circular shaft is investigated by using experimental test and a numerical analysis.A framework for determining the earth pressure distribution on the basis of both centrifuge model test and 2D FE analysis results is introduced. Through these studies, it is found that the lateral earth pressure acting on a vertical circular shaft considering arching effect is about 80% smaller than that calculated by Rankine's theory. It is also found that arching effect is highly dependent on the shaft diameter, the bearing condition and the flexural modulus of shaft. And it is shown that arching effect of soil is more significant for flexible vertical shaft than for rigid vertical shaft embedded in weathered soil.
