DeepEX 2015 - continued innovation and excellence! Continuing with our dedication and passion for deep excavations, DeepXcav has been

renamed to DeepEX 2015. DeepEX introduces new unique features that extend the

software capabilities. DeepEX is now the only deep excavation design software with all

major calculations reported in equation format.

Truly yours,

Dimitrios Konstantakos, P.E.

What does DeepEX do? DeepEX is a software dedicated to the analysis and design of embedded wall

excavations. DeepEX performs a wide range of geotechnical and structural calculations

to examine almost any type of problem.

How is the new interface? We have taken great care and effort in the simplified 2015 interface. Now the new

General tab includes practically all the information you need to create a model.

Supports and loads can be drawn in from two drop down buttons on the top left. Other

dialogs have also been simplified with general data being separated from advanced

information.

What are the analysis methods? DeepEX is the only software in its category that can analyze a wall with limit-equilibrium

or elastoplastic methods. In the elastoplastic analysis, the soil is divided in active and

passive non-linear soil springs. In the elastoplastic analysis, the lateral soil pressures

depend on the soil properties and the proposed construction stage history.

What are the implemented design standards? DeepEX implements a wide range of US and European design standards. These

include: AISC, ACI, AASHTO, BS, EC2, EC3, EC7, DIN, DM08, etc.

What about slope stability? DeepEX can perform slope stability analyses with the Bishop, Janbu, and the

Morgenstern-Price method. Soil nails can also be included in the stability analyses.

Now the axial wall capacity can be included in a slope stability analysis.

What about AASHTO Load Combinations? DeepEX reports all factors with their corresponding AASHTO type notation when an

AASHTO type load combination is specified. PENN DOT load factors have also been

implemented.

What about Eurocode 7? DeepEX 2014 can generate all design approach cases for Eurocode 7, 8, and the

Italian, Greek, German, and French adaptations. Partial factors can be adapted to

match any local EU country standard.

How can I optimize a deep excavation? A new button permits you to let the program optimize all items of your model:

What about reporting? Reports can be customized and exported to PDF and MS Word formats. The new

reports have been improved and new results outputs are available that can be

presented in full portrait, half page, or landscape formats.

What is new!

New – Move ground surfaces and water tables by dragging:

Take your mouse over the ground surface. Press and hold the left mouse button when

the surface highlights. Move the surface elevation with your mouse.



Deep Excavation LLC


New Wizard: We have improved the wizard making it more intuitive. You can now

select the type of excavation to be modeled directly from the wizard.



Deep Excavation LLC


New – Interactive tracking of result graphs:

Now in the 2015 version, trace one of the graphs with your mouse and the value at the

elevation will appear on your screen.

New Limit-Equilibrium Analysis Options:

New - Simple span analysis with negative moments: The 2015 version offers new

options for limit-equilibrium analysis. One of the options is analyzing the wall beam with

a simplified approach where negative moments can be applied. The percentage of

negative moments can be defined by the user.

While this is a simplified analysis method, it has been quite popular with transportation

authorities in the US. A major difference to the FHWA beam approach for this method

is that fixity is not assumed at the excavation level but at the point of zero net loading

below subgrade. This approach tends to produce slighly greater bending moments

compared to the FHWA GEC-4 beam analysis approach.



Deep Excavation LLC


New - User defined passive earth pressures: You can now define your own user

defined passive earth pressures:

New – Passive pressures with user defined passive slopes and starting pressure:

Very often design specifications call for specific passive pressure slopes to be used.

While we have found out that these specifications are some times inconsistent with

geotechnical mechanics the program offers you the ability to calculate passive

pressures in this way.



Deep Excavation LLC


New – Ignore passive resistance over specified depth:

Full Reporting of calculations: Nothing is hidden, easily review all calculations for

limit-equilibrium analyses and for structural checks of walls and supports.



Deep Excavation LLC


Full 3D Model Cost and Quantity Estimation

The cost estimation has been extended to the 3D model. Now the program can

estimate all quantities and costs for your full excavation saving you time.



Deep Excavation LLC


Improved Waler and Frame Analysis module: Now you can create excavation

support frames with wales and struts. Easily optimize steel sections and view results in

a comprehensive manner. The frame analysis capabilities have been extended and the

3D forms have been improved.

Original analysis with overstressed members

After 2 minutes the frame plan with optimized sections

Automatic slope stability search: Quick command to start the radii from the wall

bottom, ability to include axial geotechnical pullout resistance for the walls.

Technical Characteristics Non-linear elastoplastic analysis, that can include up to two walls. Limit-equilibrium analysis methods, free earth, fixed earth, Blum's method, apparent earth

pressures, FHWA pressures, etc. Integrated structural and geotechnical features. Multiple support types available: Tiebacks, struts, rakers, slabs, fixed supports, user defined

spring supports. Thermal effects and shrinkage effects can be included on struts and slabs. Many different wall types: Soldier piles, sheet piles, secant piles, tangent piles, diaphragm walls,

SPTC walls, and combined sheet pile walls. Multiple wall beams can be activated at any stage. These wall beams can be added parallel or

at any point along each main wall. Their properties can change at any stage. Cofferdam walls and bin type walls with different assumptions. User-friendly graphical approach. Double click on any item to see its properties or results. Design and evaluate deep excavations in minutes. Use the DeepEX wizard and your model can

Cost Estimation module: Complete with local city cost factors and other data,

customize your own cost data and provide quick cost estimates that consider both

installation and material costs.

Waler supports and circular shafts: Circular walers, either steel or concrete can now

be included! The waler stiffness is computed at the waler center span and the waler is

treated as an equivalent lateral spring.



Deep Excavation LLC


Combined sheet pile walls: DeepEX now includes combined king pile-sheet pile walls

with ARCELOR databases included. Single king pile walls, double king pile, and pipe

pile combined walls can be included.

Steel strut sections: Double struts with cross-laces and hollow square sections are

the request of many Asian customers.

Grouted minipiles as anchors: DeepEX can now compute the geotechnical strength

for slanted micropiles using a dedicated skin friction value or an effective stress

approach.
