Dams and levees are essential to our society. They protect us from floods and other natural disasters, and the consequences can be disastrous if they fail. Cone Penetration Testing, or CPT, is a subsurface investigation method that can determine the strength and stability of the ground supporting these massive structures. This high-resolution data can help geotechnical engineers identify potential problems and implement mitigation strategies. Keep reading to learn how to leverage CPT to support the nation’s infrastructure and expand your business.
The Benefits of Cone Penetration Testing
CPT involves statically advancing a sensor probe with a conical tip up to hundreds of feet (or less) below the ground subsurface to collect in-situ readings of three main measurements: tip resistance, sleeve friction, and pore pressure. These measurements can then be used to determine the sediment’s strength and the structure’s stability by calculating several values which can generate a soil behaviour type. You can learn more here. CPT is efficient, effective, much faster, and less disruptive than traditional drilling methods.
Vertek offers low-ground pressure systems such as our tracked CPT systems and S4 CPT Sounding System, which are ideal for such areas. The S4 is particularly popular among new and experienced CPT operators because it can mount to various standard construction equipment equipped with auxiliary hydraulics.
Using Cone Penetration Testing to Support Dams and Levees
When constructing dams or levees, whether for a new project or the evaluation of an existing structure, a CPT investigation can be used to determine the subsurface sediment strength and the structure’s stability. This information is essential for ensuring these structures are safe and still sound to withstand tremendous loads from climatic events.
With the recent $3 billion investment by the federal government for dam-related projects, there will be a great need to conduct sensitive subsurface investigations to understand and evaluate these structures and if risk mitigation efforts are necessary. The U.S. Army Corps of Engineers and Bureau of Reclamation, for example, uses Vertek CPT systems to assess dams and levees around the U.S., This work will continue to expand to geotechnical firms and drilling companies in the years ahead.
