SUMMARY:Ground freezing below a river estuary
DESCRIPTION:Overview \nA new 1.48km road tunnel has been excavated beneath the Świna straits in northwest Poland using a 13.46m slurry TBM. To overcome the challenges posed by low overburden and complex geology\, artificial ground freezing was implemented to enable safe excavation for the emergency egress structures required for motorway operations. This presentation will focus on the design and execution of the ground freezing process\, including analysis of construction phase monitoring data and key lessons learned from this challenging project. \nLearning outcomes \nAttendees will learn about ground freezing under river estuaries. \nTimings \n17:30 – 18:00 – Registration \n18:00 – 18:50 – Presentation \n18:50 – 19:00 – Questions \nIf attending online\, please log in at 17:55. \nSpeaker \n \nAnastasios Konstantinou \nDesigner\, Systra \nAnastasios (Tassos) is a seasoned geotechnical engineering specialising in underground infrastructure design. With a strong background in TBMs\, NATM\, cut and cover structures\, deep excavation as well as soil and rock slope stability\, Tassos brings a comprehensive skill set to his role. Originally from Greece\, Anastasios joined the SYSTRA team in 2018 and is currently the design package lead for the TBM Tunnel Segmental Lining design on the Suburban Rail Loop East\, Work Package C based in Melbourne.
