Soil-Structure Interaction of a Pile Wall

Abstract: The construction of an industrial unit required a 10-meter-deep excavation at the toe of a steep natural slope with signs of previous instabilities. The adopted solution was a soldier pile wall with several levels of ground anchors. On the other hand, several remediation measures (horizontal drains, driven steel piles (rail segments), ground anchors and bolted steel meshes) were also used to increase the slope stability and reduce earth and water pressures on the pile wall. Limit equilibrium and finite element analyses were performed for the design of those remediation measures. Finite element analyses provided useful information about bending moments in the pile wall and anchor forces. Detailed instrumentation, namely inclinometers, anchor load cells and topographical surveying, was used to monitor the performance of the wall and the slope. After construction completion, additional numerical analyses (Winkler beam method) and comparisons between field measurements and numerical analyses were performed to gain a deeper understanding of the soil-struc-ture interaction.
