ParatiePlus 26.0.1: Advanced Geotechnical Software for Deep Excavation & Retaining Walls

ParatiePlus 26.0.1 is a specialized 2D finite element software for the analysis and design of deep excavation support systems and retaining walls. Developed by the French company Résipierre France (part of the Terrasol group), ParatiePlus uses the stress-strain method (also called the “Civil Engineering method”), which directly models the interaction between the retaining wall and the surrounding soil using the finite element method (FEM) . Unlike the classical limit equilibrium approach (e.g., Blum method), ParatiePlus accounts for the actual stiffness of the wall, supports (struts, anchors), and soil, making it essential for complex excavation geometries and serviceability (settlement) analysis . Version 26.0.1 continues the evolution of this industry‑standard tool, adding a Sensitivity module for probabilistic analysis, support for tieback anchors, and updated code references (Eurocode 7, NAFRA) .

????️Primary Users

• Academic Researchers & Geotechnical Specialists studying soil-structure interaction and excavation-induced ground movements. .

⚡ Key Features & Capabilities

???? Wall & Support Types

Wall Types:

• Cantilever walls

• Single or multi‑propped walls (struts, tiebacks, rakers)

• Anchored walls (prestressed or passive anchors)

• Soldier pile walls, sheet pile walls, diaphragm walls, secant pile walls, contiguous bored pile walls

Support Types:

• Struts (rigid or elastic)

• Tieback anchors (prestressed or passive)

• Rakers (inclined struts)

• Ground anchors (multi‑level)

???? Soil & Groundwater Modeling

• Soil constitutive models: Mohr‑Coulomb, elastic‑perfectly plastic, soft soil creep

• Multi‑layer soil profiles (stratigraphy)

• Phreatic surface definition (water table)

• Excess pore pressure dissipation (consolidation)

• Seepage forces (steady‑state)

????️ Construction Stage Sequencing

• Model complex staged excavations (e.g., top‑down construction)

• Install/remove struts and anchors stage by stage

• Apply surcharges (adjacent buildings, construction equipment)

• Track wall displacements, bending moments, shear forces, ground settlements over time

???? Output & Design

• Wall displacements (lateral deflection)

• Bending moments, shear forces, axial forces

• Strut and anchor forces (tension/compression)

• Ground surface settlements (trough)

• Soil pressures (active, passive, at‑rest)

• Reinforcement design (steel or concrete sections)

???? Sensitivity Analysis (New in v26)

• Probabilistic sensitivity module (partial factor or global factor calibration)

• Monte Carlo simulation for parameter uncertainty (soil properties, surcharge loads)

• Influence ranking of input parameters on wall displacement and internal forces
