Soil Types (Quick Clay)

Infrastructure development usually involves changes to local slopes. Excavation or backfilling works affect slope stability. A sound geotechnical understanding is necessary to ensure safe ground conditions during and after construction.

Soil properties are commonly determined by a set of different geotechnical borehole investigations, as well as soil samples tested in geotechnical laboratories. Parameters such as clay-,silt-, sand content, salinity and water saturation govern geotechnical properties. These are directly related to the geophysical model we extract from the airborne geoscan.

We combine geotechnical observations and the geophysical model with AI-based algorithms to provide a holistic model of soil parameters.

Quick clay is a special type of glaciomarine clay that poses a significant land slide hazard in the northern hemisphere’s high latitudes. Norway, Sweden, Finland, Russia, and Canada are prone to quick clay occurrences. In Canada, quick clay is often referred to as Leda or Champlain Sea clay. Projects in these areas need to manage the risk for quick clay landslides.

Post-glacial rebound since the last ice age has exposed formerly marine clay to fresh ground- and rainwater. This has led to leaching of the originally saline pore water. The lack of stabilizing salt ions reduces the remoulded shear strength and turns the clay to quick clay. The salt content, which is strongly correlated to electrical resistivity, is thus a proxy for quick clay occurrence. We make use of this relationship and combine geophysical models with local samples of quick clay to produce quick clay probability maps and models.
