GAP2 Lab Applied Geology & Applied Geophysics Laboratory

Activities

The research activities carried out in the laboratory mainly concern forecasting, prevention, mitigation and management of risk associated with hydrogeological hazards and with underground cavities, voids and tunnels.

By joining geological and geophysical expertise and skills, lab activities cope with a wide spectrum of applications related to environmental and civil engineering, as well as to civil protection and public safety.

As far as hydrogeological hazards are concerned, the research framework entails:

  • integrated assessment and monitoring of unstable slopes with geological, seismic, microseismic, electromagnetic and electric methodologies
  • Decision Support Systems tools to compute the probability of slope collapse and hazard level
  • Residual risk in the emergency phase
  • Forecasting and prevention programs, as well as emergency plans
  • Numerical modelling addressing slope stability and solid transport

Regarding underground cavities, with a particular focus on abandoned mining sites, sinkholes and karst voids, the research areas are:

  • assessment and monitoring of underground voids with seismic and electromagnetic techniques
  • assessment of geological and hydrogeological risk and emergency plan definition

As far as geophysical activities are concerned, the main capabilities regard:

  • development of novel hardware and localization algorithms to locate survivors trapped under rubble by means of microseismic techniques
  • non-destructive investigations of civil engineering structures with ultrasound devices and Ground Penetrating Radar
  • detection and localization of utilities and water leakage in water pipeline networks
  • seismic microzonation with MASW and HVSR techniques
  • electromagnetic investigations of snow cover

Instruments/Software

Acquisition systems for near-surface seismic investigations (P-and S-wave reflection and refraction; multichannel analysis of surface waves)

  • commercial packages and proprietary software to process seismic refraction, reflection datasets, MASW, refraction and transmission tomography
  • equipment and software for seismic microzonation
  • equipment and software for GPR surveys, both reflection and tomography
  • equipment and software for electrical resistivity tomography
  • laser scanner and TDR to monitor unstable areas
  • numerical modelling software addressing the behaviour of unstable slopesnti

Services for companies

  • forecasting and prevention programs, emergency plans at local and regional scales
  • integrated monitoring of unstable slopes and definition of critical thresholds for alarm generation
  • hazard and risk maps related to hydrogeological risk
  • numerical analysis of landslides to evaluate stress-strain conditions
  • assessment of geological risk related to underground cavities and abandoned mining sites
  • localization of survivors trapped under rubble, detection and localization of utilities and water leakage in water pipeline networks
