Platform for integrated monitoring data management applied to an instrumented slope in southern Brazil: Plataforma para gerenciamento integrado de dados de monitoramento aplicada a um talude instrumentado no sul do Brasil

The monitoring of slopes and geotechnical structures is fundamental for guaranteeing safety and improving the knowledge of soil behavior. This study evaluated the use of a platform for integrated monitoring data management applied to an instrumented slope. The slope, known as “Morro do Boi”, is located in BR-101 highway, in Santa Catarina state, Brazil. The instrumentation was installed in 2012 during the execution of a stabilization system designed to contain an unstable soil mass, and allows the verification of positive and negative pore pressure, deformations of the soil mass and the precipitation. In addition, the structure, composed by passive anchors and flexible metal mesh, is monitored with crackmeters, strain gages and load cells. Until May 2018, the historical data comprising 6 years of monitoring was automatically registered by a datalogger hourly, with manual download. On June 2018, the remote dispatch of the data was implemented and the management of this information is done through a web-based platform. This tool has been extremely useful for the ease of visualization, data management and logistical efficiency, allowing the creation of a rapid alert system in cases of variation of some parameters that could trigger landslide.
