Abstract
A spatial sensor network was tested during five experiments on a landslide simulation platform. Here, a landslide was triggered by means of simulated rainfall. The sensor network currently incorporates in situ sensors and two stereo imaging systems. In future, these sensors will be installed on a real-scene slopes in Sichuan Province (South-West China). The paper focuses on the results of two latest landslide simulation experiments. While one experiment ended with a partial failure, the second one showed a complete slope collapse. In the first part of the study, the full data series are investigated to perform correlations and common pattern analysis, as well as to link them to the physical processes. In the second part, four subsets of sensors located in neighbouring positions are analysed. Although the small scale of the simulated experiment probably influenced the results, these experiments allowed ascertaining which sensors could be more suitable to be deployed on the real-scene landslide sites.
