Tie-Back Wall for a Deep Excavation

The German Society for Geotechnics has worked on establishing some benchmark problems for validating numerical analyses. One of the benchmark examples is about the construction of a tie-back wall for a deep excavation in Berlin.

Part of the numerical validation program of the Society included holding an analysis competition where information about the project was made available to those wishing to model the construction and make a prediction of the wall performance. The lateral wall deflection was measured with an inclinometer and the main objective was to see if the analyst could predict the lateral wall deflection. The measured results were not made available to the analyst until the end of the competition.

SIGMA/W now has sufficient features and capabilities to simulate the construction sequence for this excavation, and obtains close agreement with the measured wall deflections.

Banff Geotechnical Modeling Workshop

The September workshop in Banff, Canada is almost full. Accommodations at the workshop location are limited, so if you are hoping to stay at the Banff Centre, reserve your seat now.

Remember that we have expanded the workshop to include an optional 4th day (September 18th). The format of this extra day will be flexible and will allow participants to choose from a series of concurrent specialized sessions on various topics.

Please visit the Banff Modeling Workshop page for full details.
