The Cone Penetration Test (CPT) is commonly used to determine the sub-surface stratigraphy in place, it is to estimate geotechnical parameters of the materials present.
Geotechnical engineers typically use a CPT test to determine the necessary construction requirements for infrastructure – roadbeds, bridges, buildings.
Due to the sensitive electronics inside the cone, it must be pushed to depth by static push methods. The CPT test method consists of pushing an instrumented cone into the ground at a controlled 2 cm/sec push rate.
The most common measurements being collected are cone tip pressure, sleeve friction, pore pressure and tilt angle. Additional sensors can be added like seismic, or other geo-environmental logging tools.
