Title:
Abstract:	Der Nachweis der Standsicherheit von nicht-ebenen Erdschlitzen, z. B. an einer Schlitzwandecke, ist mit dem vorhandenen Normenwerk nicht abgedeckt und auch nicht einfach zu erbringen. Dieser Artikel soll daher einige Erkenntnisse aus Vergleichsberechnungen mit sog. erweiterten DIN 4126-Ansätzen und 3D-Simulationen mit FE-Methoden hinsichtlich des Einflusses der Schlitzdicke auf die Nachweisführung von Eckschlitzen mitteilen. Die Grundsätze der Nachweisführung mit vereinfachten ebenen Ansätzen für die Eckschlitze wurden in [1] dargelegt. Aufgrund der Anregungen aus der Anwendung in der Praxis wurden Ergänzungen vorgenommen, um das Verfahren auch für relativ dicke Erdschlitze sinnvoll anwenden zu können. On the stability of slurry corner trenches. The overall stability calculations of non planar open trenches used in the course of the D-Wall construction is not covered by the existing regulations in Germany and even not an easy task. The present paper provides new findings arisen from 3D FE-simulations and comparisons with analytical models based on extended model of the DIN 4126 in order to ascertain the influence of the width of non-planar D-Wall panels on the stability of the open trench. The basic ideas for the design calculations dealing with simplified models for non-planar panels have been presented in [1] and due to the feed back from the application in practise some modifications of the simplified analysis have been carried out in order to facilitate the application of the model for large panel widths.
