SANAS T1018
Public test guide
Pushes an instrumented cone into the ground to obtain a continuous profile of resistance with depth.
Plain-language explanation
The project specification controls the exact method and acceptance requirement.
A cone is advanced at a controlled rate while tip and sleeve responses—and where applicable pore pressure—are measured.
CPT rig and reaction system, instrumented cone, depth encoder and data-acquisition system.
Continuous resistance profiles that support soil-behaviour interpretation and identification of layer changes.
Useful for foundation, settlement and ground-model investigations where continuous in-situ information is required.
Typical test sequence
Set up and verify the equipment at the test point
Advance the cone while recording measurements continuously
Process the profile and correlate it with site and laboratory information
