Abstract

The article presents the results of monitoring the horizontal displacements of the 15.5 m deep excavation wall made of tubular concrete piles. Actual and calculated values of the horizontal displacements of the wall are given. There is a significant increase (more than calculated) in the actual displacements of the wall towards the excavation due to the irregularity of construction order. The interpretation of the monitoring results is considered concerning the excavation wall that preserves stability. The monitoring results are suggested to be applied to the design of the excavation walls.
