Wielkośrednicowe tunele TBM w trudnych warunkach geologicznych – ograniczenia, ryzyka i dobre praktyki – studium przypadku Dubai Stormwater Tunnel

The design and construction of tunnels using tunnel boring machines (TBMs) (segmented lining tunnels) depend primarily on the type of ground (hard rock, weak rock, soft soils, cohesiveless soils, hydrogeology, etc) where the work will be carried out. The selection and design of the TBM, the launching and landing systems, and the excavation management are all determined by the ground type. Many of these key aspects become more complex when using large TBMs, as in the Dubai Stormwater Drainage Project. This project is a good example of how the design of the large TBM (10m of internal diameter of tunnel and 11.5m cutterhead outer diameter), the launching systems, the excavation strategies in a hetereougeneus weak rock, and the precast segmented lining design can be perfectly tailored to the ground conditions to minimize construction risks and ensure optimal TBM performance and a good production of construction works.

Chartered Civil Engineer – MICE CEng, Institution of Civil Engineers. London (UK), has extensive experience as a Technical Director, specializing in the design and construction of all types of tunnels (hard and weak rock tunnels, soft soils tunnels, TBM tunnels, NATM tunnels, pipe jacking tunnels, etc), with broad expertise in tunnel boring machines (TBMs).
With over 27 years of experience, he has successfully contributed to a wide range of major tunnel projects worldwide (high-speed rail infrastructures, metro tunnels, sewer and stormwater and sewages infrastructures, hydropower and mining infrastructures). He has led the design of projects such as Crossrail in London and the Dubai stormwater drainage system, and is currently directing the design of the Second Avenue subway in New York.
His experience also encompasses risk management in tunnel projects, and he possesses in-depth knowledge of tunnel boring machine (TBM) selection and design for segmented-line tunnels and pipe jacking systems.
