Fiber Optic Sensing for Landslides Early Signs Monitoring and Consequences Assessment
NSG2021 27th European Meeting of Environmental and Engineering Geophysics(2021)
摘要
Summary A variety of landslides such as mud flow, rock fall and rock avalanche can be detected with Distributed Acoustic Sensing (DAS) when they occur. The consequences of the event, and, most importantly, the very early signs of its development can be assessed by Distributed Strain Sensing (DSS). The combination of DAS and DSS instrumentation helps to mitigate geohazard risks along infrastructures crossing challenging environments.
