Workshop on Deep Excavation in Clay – Short term vs long term behaviour

       
TypeWorkshop
Date 08/12/2017
Location Delft
Organizer Plaxis bv

Price €650

Registration closed

This workshop demonstrates the practical use of Plaxis 2D for deep excavation in clay. It particularly focuses on some of the most relevant modelling issues for such type of analyses:

  • Undrained modelling in PLAXIS
  • Soil test facility for the evaluation of undrained shear stress
  • Dewatering
  • Hardening Soil model vs Mohr-Coulomb model
  • Influence of small strain stiffness
  • Normally consolidated versus over-consolidated clay

For solving practical problems the PLAXIS 2D 2017 computer program will be used. It is recommended that participants already have experience with the PLAXIS 2D software.

Format

The workshop starts at 9:00. The program format consists of 3 lectures (approx. 45 mins each) and 1 exercises (approx. 90 mins. each) and 1 extensive case study (approx. 90 mins) with full tutoring and discussion. The workshop will be completely in English. The organizers reserve the right to make any necessary amendments to the format or schedule.
