Anchored Secant Pile Wall - Analysis and Optimization

Example: Secant Pile Wall with Tiebacks - Analysis and Model Optimization

This example presents the design of a 43ft excavation with a reinforced concrete secant pile wall, supported by three levels of tiebacks. The model and analysis have been prepared with the DeepEX - Shoring Design Software. In the example video, we present how to generate the model using the DeepEX Model Wizard, how to perform the analysis using the Limit Equilibrium Analysis Method and how to evaluate the results and optimize all model items (wall and supports) structurally and geotechnically.

A. Project Description

The 43ft deep excavation is supported by a reinforced concrete secant pile wall (originally 2ft diameter reinforced concrete piles), supported by 3 levels of anchors. Three soil layers are considered, and a 0.6 ksf surcharge is included at the top. The model is created automatically with the DeepEX model wizard. The figure below presents the originally created anchored wall model (last construction stage).

The analysis is performed with the DeepEX software, using the classical Limit Equilibrium Analysis method. Once the analysis is completed, we present how to evaluate the results and how to optimize several items (wall structural section, tieback bonded part lengths etc) manually and with the use of the automatic optimization tools of DeepEX.

C. Anchored Wall: Limit Equilibrium Analysis Results & Model Optimization

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. All model items (walls, supports) can be structurally and geotechnically optimized easily, either manually (by accessing and modifying the structural sections, spacings, lengths etc) or with the use of the software automatic optimization tools.

The following images present typical results from the originally generated and the optimized model, as well as, the model optimization procedures.
