Purpose and BackgroundCarbonate and evaporite geologic formations underlie a large portion of the world. These formations contain soluble compounds that result in portions of the formations dissolving over time to produce cavities, conduits, enlarged joints, caves, etc. The landforms resulting from these features are referred to as karst. Karst poses many geotechnical concerns such as subsidence, sinkholes, uneven structural support, high groundwater production, and groundwater sensitivity to contamination.
Locating and characterizing karst features at depth is a challenging task. Even large features can easily be missed by conventional borings and may not be detectable by some geophysical methods. This makes it necessary to employ a specially focused investigation that incorporates geological, geotechnical, statistical, and geophysical approaches to evaluate risks and determine the appropriate level of investigation.
This presentation includes a brief introduction to karst and the associated geotechnical issues. The instructor discusses and provides examples of methods and strategies for investigating and characterizing various aspects of karst.
Primary Discussion Topics
- Geotechnical issues in karst
- Geologic associations of karst features
- Applications and limitations of various methods for investigating in karst
- Integrated approach to investigation
