Presentation outline This presentation will give an overview of the different soft ground tunnelling techniques used on the Thames Tideway Project. The main focus will be on the west section of the Thames Tideway Tunnel in London, where an earth pressure balance tunnel boring machine and sprayed concrete lining methods were employed. The talk will [...]

Overview This event offers invaluable insights into improving road tunnel ventilation systems. Hear first-hand from experts who collaborated with Australian road tunnel operators to enhance their ventilation using advanced simulation tools. Learn how Ventsim DESIGN, a 1D network flow simulation tool with a 3D graphical user interface, was adapted for tunnel-specific challenges like jet [...]

Presentation abstract: Cavidrain Invert geocomposite systems are used to form a drainage layer beneath the road pavement of tunnel floors. The use of Cavidrain Invert offers a number of advantages over more traditional methods (which use crushed stone and pipes) such as: (i) reduced excavation (as they form a much thinner layer compared to [...]

The rapid development of mechanised tunnelling in the last decades has increased the tunnelling community’s focus on the environmental aspects of tunnel construction. The excavation carried out by using EPB (Earth Pressure Balance) machines often requires the use of foaming agents, specific products that are added to the medium intended to be excavated, in order [...]

Topic: Practical Aspects of Segmental Tunnel Lining Design After several decades of continuous progress, mechanized tunnelling has now become the main method applied in almost all types of geology, all sizes, and in increasingly shorter lengths. The predominant excavation support system for TBM tunnels consists of a one-pass precast concrete segmental liner which in [...]

This instalment of the Lunchtime lecture series will focus on practical Face Stability Issues.
