Rectangular Shape Excavation - LEM, NL, 2D &3D FEM Analysis


Model simulation, comparison between LEM, Non-Linear and FEM analysis, 3D FEM model analysis


Rectangular braced excavation - 3D Finite Element Analysis in DeepEX

This example aims to demonstrate the effortless generation of any deep excavation model using our advanced DeepEX – Shoring design software, encompassing both 2D excavation cut sections and 3D models. Additionally, it illustrates how to analyze these models using various methods, including Limit Equilibrium, Non-Linear Analysis, Finite Element Analysis, and the 3D Finite Elements approach.


In this scenario, we will generate a 2D section and a rectangular 3D model of a 6-meter-deep excavation, supported by secant pile walls and a single bracing level with steel struts. For a comprehensive analysis, two distinct 3D surface loads will be considered, simulating adjacent structures near the excavation perimeter.

The evaluation of the 2D sections will employ three different approaches:

- The classical Limit Equilibrium method

- The Non-Linear analysis method with elastoplastic Winkler springs

- The 2D Finite Element Analysis approach

Additionally, a 3D model will be generated and assessed using the 3D Finite Element Analysis approach. This analysis will present visual representations of calculated shadings for soil, wall, and support stresses, along with displacements.
