Talren 4 Brochure

The latest design tool for checking the stability ofgeotechnical structures with or without reinforcementsTALREN 4STABILITY OF SLOPES AND ANCHORED WALLSTalren 4 is ideal for checking the stabilityof natural slopes, cut or fill slopes, earthdams and dikes. It takes into accountvarious types of reinforcements, such as:anchors and soil nails, piles and micropiles,geotextiles and geogrids, steel andpolymer strips.New user-friendly graphical interfaceWith for example:u Definition of the profile using a mouse, rulers and a grid. Other features include pop up menus andchoice of soil colours.u Ability to load background drawings (.jpg and .gifformats) and adjust to scale.u Several construction stages and calculationalternatives can be handled in the same file.u Tables illustrating main soil, load and reinforcementdata.u Various output options for graphical display andtables (shadings, forces in reinforcements, detailedresults for each failure surface, etc.).u Wizards and databases to help produce the bestmodel and choice of input data (partial safetyfactors, choice of qs, etc.).Links with Plaxis v8 (finite element program)u Ability to load Plaxis v8 files (geometry andmain soil characteristics).u Ability to import Plaxis v8 pore pressuremeshes (with selection of the Plaxis stage to use).FICHE TALREN 4 GB:FICHE TALREN 4 GB 05/05/11 14:33 Page1TALREN 4Minimum hardware requirements PC-compatible computer with:• 1.4 GHz processor• 256 Mb RAM• USB port• 300 Mb free hard-disk space• Windows® XP/2000/2003/7 (32/64 bit)New calculation functionalitiesu Automatic search option for circular failuresurfaces (no need to define a manual grid).u No limit on the number of elements you candefine (points, layers, reinforcements,hydraulic mesh, etc.).u Future upgrade option for Talren 4 users:calculation method based on limit analysistheory (J. Salençon).And TALREN still benefits from……extensively used methodsu Limit equilibrium calculation along potentialfailure surfaces using the Fellenius, Bishop orperturbations methods.u Ability to take into account hydraulicconditions.u Seismic loads are taken into account by thepseudostatic method.…a specific treatment for each type of reinforcementu Each inclusion can work in: tension,compression, shear, bending.u Ability to use a combination of differentfailure criteria for the reinforcements and thesoil to accurately model all the mobilisedforces (principle of maximum plastic work).…a design method validated as part of theFrench National Research Project Clouterre The part of the Clouterre report dealing with thedesign of soil nailed walls is largely based on thetheories used in the development of Talren 4,which is recognised as one of the best designtools for reinforced soils.AgentImmeuble Central Seine 42-52 quai de la Râpée 75583 Paris Cedex 12 FrancePhone: +33 (0)1 82 51 52 00Fax: +33 (0)1 82 51 52 99 www. terrasol.com software@terrasol.comUne société du groupeFICHE TALREN 4 GB:FICHE TALREN 4 GB 05/05/11 14:33 Page2
