%K Eurocode 7, ultimate limit state HYD, excavation bottom stability
%X The present paper addresses the issues of excavation bottom stability as ultimate limit state HYD of the Eurocode 7. It has been shown that with excavations surrounded by sheet pile walls, the two conditions for ultimate limit state HYD as provided in EC7 procedure different values of the global safety factor. For the stability condition expressed in forces and weights affecting the column of soil at a sheet pile wall, the global safety factor is F = 1.5, while for the condition expressed terms of effective stresses this factor is F = 3. The methodology of calculating the excavation bottom stability according to EC7 was exemplified by a linear excavation.
