Case Study Webinar Series Numerical Modelling of a Metro Pedestrian Access Tunnel in Istanbul 24 September 2020 (Thu.) 7AM GMT / 8AM London / 9AM CET / 2PM Jakarta / 3PM SG, KL, KK, Perth / 5PM Sydney / 7PM Wellington | Duration : 50 Min

>> Blog | 5 Common tunnel designs to consider 3D effects


This project includes a numerical design of a metro pedestrian access tunnel between a metro line and shopping mall with a NATM methodology. In Istanbul, due to a construction of a new shopping mall, it is required to have an access tunnel from existing metro line to the entrance of the shopping mall. Therefore, by using MIDAS GTS NX, a NATM tunnel with a length of 25m is modelled and designed.

During this webinar, Mr. Arslan will present the geological and the geometrical information of the project and will discuss how to apply the numerical modelling in this project case. As the construction of the tunnel has been finished, he will show the construction stages and the corresponding construction photos for the webinar attendees.
