MIDAS Geotech - Free FEM Online Courses in 2021 Staged Excavation and Construction of a Shield Tunnel Nov 09, 2021 (Tuesday)
- Time 1: GMT 6 am / SGT 2 pm / AEDT 5 pm / NZDT 7 pm
- Time 2: GMT 11 am / CET 12 pm / CAT 1 pm / GST 3 pm / IST 4:30 pm | Duration : 60 Min

This online course session will focus on tunneling in the soft ground using the Shield TBM using the non-linear static construction stage method. 


The Shield TBM method is more widespread in urban areas or in areas with a sizeable human population. To reduce the effect of the construction process, this method is widely considered as a worthy replacement for NATM Tunnels. This tunneling method can be applied in soft ground materials or squeezing rock/soil, therefore it is essential to simulate accurately in 3D. 


In this 1 hour program, GTS NX will be used to demonstrate the modeling of the Shield TBM Tunnel in 3D and all the necessary ground states and applications of various forces on the soil and structural elements will be demonstrated. 


All the different training examples through the webinar sessions and certification tasks are designed to enhance the understanding of training. Engineering professionals and graduates are invited to attend this course for free.
