Tunnel monitoring – chapter 1 – Philosofy, entrance, cross sections and excavation face
In this set of video (Tunnel monitoring) we would like to present some monitoring solutions that could be used during tunnel excavation. The chapter 5 is dedicated to the monitoring solutions for the buildings above excavation zone and will close the set of video with simple description of data acquisition systems and WMS web monitoring […]
What is a piezometer, how it works, available technologies and models
With this presentation, we would like to introduce the meaning of «piezometers», their classification (open and close circuit piezometer), method of reading (deep meter or electrical piezometers), available technologies (piezo resistive or vibrating wire sensor) and the main models available. Electrical piezometers include common vibrating wire piezometers, heavy duty piezometers, multipoint piezometers, removable transducers for […]
Mining monitoring instrumentation
Mine monitoring system shall be designed starting from the mine-typology: open pit mine or underground mine (cavern). In open pit mine is really important to monitor the stability of rock/soil walls with inclinometers, incremental extensometers, piezometers and wire extensometers. In underground mining become critical to monitor the stress and displacements of the excavated rock and […]
Landslide monitoring instrumentation
Landslides are monitored following different parameters like landslide type, layers type, displacement speed, etc… The most utilized geotechnical instruments for this purpose are the inclinometer casings (or inclinometer tubes) able to control horizontal movement into the ground. Inclinometer casing can be read with portable inclinometer system or with IPI / BH Profile probes (automatic Inclinometer […]
Dam safety and monitoring
Planning a performance monitoring program is an essential component of successful dam construction and operation. Dam monitoring is recommended to ensure the safety of a dam. Geotechnical instrumentation and structural instruments are used to determine the initial conditions at dam site, monitoring during construction, initial filling and drawdown; and assist long-term monitoring. One of the […]
