Diaphragm (Slurry) Wall Braced with Struts - 2D Section Design

Braced Excavation Example: Diaphragm Wall with Steel Struts (2D Section Design)

This example presents the design of a 30ft excavation with a reinforced concrete diaphragm wall braced by two rows of struts. The model and analysis have been prepared with the DeepEX - Shoring Design Software, using the DeepEX 2D analysis methods (Limit Equilibrium - Non-Linear Analysis).

A. Project Description

The 30ft deep excavation is supported by a 2ft thick diaphragm wall and two levels of cross-lot struts. Four soil layers are considered, and a 0.8 ksf surcharge is included at the top. The figure below presents the optimized braced excavation model.

The analysis is performed with the available analysis methods in DeepEX software basic version - Limit Equilibrium Analysis and Non-Linear Analysis (Elastoplastic Winkler Springs). Once the analysis is completed, the structural wall and strut sections are quickly automatically optimized the and required wall depth is determined

C. Braced Excavation Limit Equilibrium and Non-Linear Analysis Results

DeepEX can perform full structural and geotechnical design of all project items (walls and supports). The calculated results (soil and water pressures, wall moment, shear and displacement diagrams, support reactions, structural and geotechnical check ratios and more) can be presented both in tables and graphically on the model area. DeepEX can analyze and present results for all construction stages, allowing the designer to review the full project history and take important decisions for the most efficient model optimization.

The following images present typical results from each analysis method.
