For detailed information on the available program features, the user is referred to the Reference Manual. The latter can be found in the Material Models Manual, as included in the full manual, and theoretical background is given in the Scientific Manual. The Tutorial Manual does not provide theoretical background information on the finite element method, nor does it explain the details of the various soil models available in the program. The tutorial lessons are also available in the examples folder of the program directory PLAXIS 3D Tunnel and can be used to check your results. It is further recommended that the lessons are followed in the order that they appear in the manual.

It is helpful, but not essential, that users have experience with the standard PLAXIS (2D) deformation analysis program. Users are expected to have a basic understanding of soil mechanics and should be able to work in a Windows environment. The various lessons deal with a range of interesting practical applications and cover most of the program features. This Tutorial Manual is intended to help new users become familiar with the PLAXIS 3D Tunnel program. This concept enables new users to work with the package after only a few hours of training. The calculation itself is fully automated and based on robust numerical procedures. The simple graphical input procedures enable a quick generation of complex finite element models, and the enhanced output facilities provide a detailed presentation of computational results. The PLAXIS 3D Tunnel program is a finite element package that has been developed specifically for the analysis of deformation and stability in tunnel projects. 6-11Īppendix A - Menu structure Appendix B - Calculation scheme for initial stresses due to soil weight 5-15 Stability of a Diaphragm wall excavation (lesson 4). 4-15 Tunnel Heading stability (lesson 3).
