Deep excavation monitoring

Deep excavation monitoring in urban area, Grand Paris Project. In this huge project Sisgeo installed a large number of geotechnical instruments.

What is deep excavations monitoring? Deep excavation monitoring refers to the process of measuring and analyzing the behavior of soil and structures during excavation works to ensure safety and stability. This monitoring is crucial because the excavation process often causes changes in the stress and strain of the soil and nearby structures. If these changes […]

TBM Tunnel monitoring

TBM tunnel monitoring is built by precast concrete sections. Into precast segments, in the factory are usually installed vibrating wire strain gauges and pressure cells.

TBM TUNNEL MONITORING What is TBM tunnel monitoring? TBM tunnel monitoring refers to the continuous assessment of structural parameters during and after the excavation of tunnels using a Tunnel Boring Machine (TBM). TBMs are widely used for efficient and precise excavation in various tunneling projects, such as subways, highways, and water conveyance systems. However, the complexity […]

NATM Tunnel monitoring

El Toyo NATM tunnel monitoring in Colombia. Sisgeo supplied piezometer PVC tubing, electric anchor load cells and MPBX borehole extensometers with vibrating wire displacement transducers.

NATM tunnel monitoring What is NATM Tunnel monitoring? Tunnel monitoring is the process of continually measuring and assessing the structural stability of tunnels, both during construction and over their operational life. In the New Austrian Tunneling Method (NATM) — also known as the Sequential Excavation Method (SEM) — tunnel monitoring is crucial. Developed in Austria […]
