Statistical evaluation of CPT measurements

Cone penetration tests help to obtain information about the nearby sub surface. A sensor is pressed up to a depth of 15 meters with a velocity of 2 cm per second. The sensors deliver the results sleeve friction, pore pressure and cone resistance. The resolution is one value per centimeter. The research deals with the repeatability of structures in the subsurface. The area in the vicinity of Loebnitz has for a long time been a region of high interest. The GFZ Potsdam performed a shear wave tomography at this location. However, the aim was a statistical evaluation of the CPT data. The development of a tool for sustainable use was accomplished.

 The results help to increase the accuracy of CPT measurements.
