INFLUENCE OF SOIL BACK PRESSURE OF THE LOWER SLOPE ON THE DISTRIBUTION OF PRESSURES BETWEEN THE ROWS OF THE PILES OF THE MULTI-ROW RETAINING STRUCTURES
Abstract
In the article, the results of the estimation of an influence of soil back pressure of the lower slope on the distribution of the landslide pressures between the rows of the piles of the multi-row retaining structures. The conditions of a stable soil and an unstable one as well as a dugout from the lower slope side have been considered. The analysis has been carried out on the basis of the distribution of the forces between the rows of the piles according to the spatial numerical model study data of the multi-row pile structures taking into account the elastic embedding of the piles below the slip surface as well as the rigidly fixed piles. It has been shown that soil development from the lower slope side in the immediate vicinity of the pile retaining structure results in a significant redistribution of the forces between the pile rows and the increase of the bending moments in the piles from the side of the dugout. A significant underload of the piles of the intermediary rows of the multi-row structures has been registered
