Underground Design

Principals of Ground Support for Tunnels

by Mr. Leo Ariza, Jacobs Australia

Friday, 23rd June 2023 // 7.00 - 8.30 pm

ABSTRACT:

Tunnel support design abides by some basic principles, which are common to most situation. These principles have allowed us to understand the possible failure mechanisms that can take place when constructing a tunnel as they remain valid for almost all tunnels in a variety of ground types, spans and end use. This presentation aims to provide a broad overview of these principles and modes of failure as well as the strategies that have been developed in order to prevent tunnel collapses and to illustrate how the modern practice deals has been simplified and compiled to allow its application around the world. It also shows how tunnel reinforcement in the form of rock bolts, sprayed concrete, forepolling and concrete are deployed to serve a specific function within an excavation.
