Geomur V2025 (Guide Complet de la Maçonnerie Durable)

Overview of GEOMUR Geotechnical Software

GEOMUR is a specialized geotechnical engineering software application designed for calculating forces on retaining walls and performing external stability checks. Developed by GEOS Ingenieurs Conseils SA, this smart geotechnical software provides engineers with reliable tools for analyzing retaining wall systems under various loading conditions.

The software calculates stresses using the CULMANN method, a well-established approach in geotechnical engineering for determining lateral earth pressures. GEOMUR enables geotechnical professionals to evaluate critical stability parameters including slipping resistance, punching shear capacity, and overturning stability for both stone wall and concrete retaining structures.

What sets GEOMUR apart is its ability to handle complex geometric configurations. The software supports inclusion of median quelconque structures across multiple floors, partially folded sheets, and various overload conditions. Earthquake loading can be incorporated through rotational geometry adjustments, following recommendations from the French Development Agency (AFD).

How to Use GEOMUR Retaining Wall Analysis Software

Setting Up a New Project
Begin by defining the retaining wall geometry. Input wall dimensions, soil parameters, and loading conditions. The software supports both stone wall and concrete wall configurations.

Defining Soil Parameters
Enter soil properties including unit weight, friction angle, and cohesion. For the CULMANN method, ensure accurate representation of soil stratigraphy, including multiple soil layers if present.

Applying Loads
Input service loads and factored loads as required. The software distinguishes between service combinations for stability checks and factored combinations for strength design. Consider including:

• Vertical loads from retained material

• Lateral earth pressures

• Surcharge loads

• Seismic loads (if applicable)

Running Stability Analyses
The software automatically calculates overturning, sliding, and bearing pressure ratios. For each service load combination, review:

• Overturning moment vs. resisting moment ratios

• Sliding force vs. resisting force ratios

• Soil pressure distributions and allowable bearing comparisons

Reviewing Results
Access results through organized tabs:

• Results tab: Controlling values and highest utilization ratios

• Soil Pressures tab: Service load combination pressure distributions

• Overturning & Sliding tab: Stability ratios for each combination

• Footing Bending tab: Flexural design results along wall length

• Footing Shear tab: One-way and two-way shear verifications
