Join us in this instructor-led course to learn the fundamentals of modelling mechanised and conventional tunnels in both PLAXIS 2D and 3D. This in-person training organised in partnership with GHD will review the most-common practical aspects of modelling tunnel excavation in soil and rock.
This 2-day instructor-led course considers the latest development in Tunnelling Applications.
Â
The course content will include:
• Mastering the fundamentals of modelling mechanised and conventional tunnels in both PLAXIS 2D and 3D,
• Optimally choosing the Finite Element (FE) model input parameters (constitutive behaviour, equivalent deconfinement levels and confinement pressure loads, ground reinforcement means) and take into account the technique of tunnel excavation in both soil and rock,
• Post-processing the calculation results to estimate the surface displacements and the structural force development inside the tunnel support.
Â
The event is organised with the support of GHD who will share their practical experience of PLAXIS 3D to pre-cast segment tunnel lining. With GHD's support a Python script was developed by Bentley to model the PCTL explicitly with joints to extract the desired output. This leading innovation which is still under development can improve the next generation of tunnel builder in PLAXIS to include the structural analysis results for PCTL.
Â
The workshop consists of 2 full days (2 x 8 hr = 16 hr). It will be held by senior PLAXIS consultants and application engineers with years of practical experience in underground structure modelling.
Â
Training attendees must bring their own laptops with the appropriate versions of PLAXIS installed (PLAXIS 2D and 3D V22). The latest software version will be sent to all participants once registered.
Complimentary temporary license keys will be provided to all course participants for the entire event duration to run the many proposed hands-on exercises properly.

Mojtaba Kashfi is a tunnel engineer with over 21 years of experience specializing in soil and rock mechanics, excavation support of excavation design, and numerical analyses for Tunnel and underground excavation. He has advanced experience in the preliminary and detailed design stages and understands the design process and associated challenges. He has developed various RS2, FLAC 2D, PLAXIS 2D and 3D to simulate ground behaviour and structure interaction in static and seismic conditions to arrive at practical solutions and recommendations.
Keivan is a leader in tunnel and underground structure design with over 17 years of experience in the project management, preliminary and detailed design, permitting, and construction management of major linear infrastructure and heavy civil projects. He has designed and constructed tunnels for a variety of utility and transit projects (0.9 m to 10.7), in varying ground conditions (from soft soil to hard rock), and has solved complex technical challenges for transit tunnels, water and wastewater facilities, roads, steel structures, soil stability, dams, and pipeline tunnels. With familiarity in designing tunnels for highly sensitive crossings of highways, gas lines, rivers, railways, and public urban areas, Keivan is an expert in the implementation of long distance tunnels, tunnelling in tight curves, projects in densely populated areas, tunnelling underneath residential buildings, stakeholder and public engagement, and tunnel and shaft cost estimation.
Richard Witasse has more than 20 years of experience in working with geotechnical digital tools and geotechnical finite element analysis software. After starting his career as a software engineer in the field of finite element analysis software for reinforced concretes structures, Richard became an application engineer and worked for the global leaders in geotechnical analysis software. Richard joined PLAXIS in 2008 and has always worked since then on geotechnical consulting, customer success and training for the many users of the most popular digital solutions for geotechnical engineering and analysis. Since 2018 Richard Witasse is Principal Application Engineer with Bentley Systems.
