Diaphragm (Slurry) Walls - Design with DeepEX

Concrete Diaphragms - Slurry Walls in DeepEX

Diaphragn (Slurry) walls can be designed with DeepEX software in the most efficient way. In DeepEX, we can design and optimize reinforced concrete diaphragms in 3 simple steps:

1. Define our sheet piles type and structural section.

2. Create our model in minutes in the software graphical interface, or using the powerfull model wizard (all construction stages).

3. Run the analysis, review the results in each stage and optimize the model (manually or with the use of the DeepEX autimatic optimization tools).

The following paragraphs present how we can follow these steps within the software and achieve an efficient model optimization in minutes.

Step 1: Define the Wall Section Type and Section Properties

Selecting the Diaphragm Wall Section Type

At any time, we can access and edit the structural section of our walls on the model area, or through the related tab of the model wizard. There, we can select our diaphragm wall section shape (straight walls, T-Panel sections). We simply need to press on any of the available pile types buttons:

Defining the Diaphragm Wall Structural Section

In the Edit Wall Sections dialog of the software we can define the section dimensions (thickness, examined panel width), as well as the longitudinal and shear reinforcement bars. The rebar size can be selected through implemented databases according to several international standards.

Step 2: Create the Model (All Construction Stages)

In DeepEX we can graphically add construction stages and draw the model on the model area stage by stage, or use the model wizard to create a model with all construction stages in seconds. Either way, we need to create a detailed staging, starting from at rest conditions in an initial stage, and then step by step generate new stages with each excabation and support installation level. DeepEX will analyze and present results for each stage, allowing us to review the full model construction process, identify the most critical stage and optimize our structural sections and support locations in the most efficient way.

Step 3: Review the Results and Optimize the Model

DeepEX can analyze any deep excavation model with several implemented analysis methods (classical Limit Equilibrium, Non-Linear Analysis with elastoplastic springs and Finite Element Analysis). After the analysis is completed, DeepEX software presents all calculation results in tables and in graphs on the model area for each construction stage. We can review all calculated stresses, moment and shear diagrams along with the structural capacities, the support and wall check structural ratios, the wall embedment safety factors and more. This way, we can have a great overview of all structural items designed by the program for each stage, and take important decisions for the efficient model optimization.

We can optimize any model fast either manually by accessing all wall and supports on the model area and edit the structural sections and support locations fast through user friendly dialogs, or use the software automatic optimization tools that can fast check and give us a variety of section solutions for all structural items on the examined model.
