However, many of the procedural requirements herein could apply to those penetrometers. When properly performed at suitable sites, the test provides a rapid means for determining subsurface conditions. Link to Active This link will always route to the current Active version of the standard. For quality assessment and proper data analysis, the frequency filtering of data is done after acquisition and not during the recording. The CPT probe records tip resistance, sleeve friction, pore pressure, and tilt angle, and the seismic adapter is used to measure the shear wave velocities. The original cone penetrometers involved simple mechanical measurements of the total penetration resistance to pushing a tool with a conical tip into the soil. Other commonly used units such as the inch-pound system are shown in brackets.
Development of seismic CPT for evaluating in-flight soil properties in centrifuge model test
Analysis and interpretation of piezocone data on the silty soils of the Venetian lagoon Treporti test site. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. Alois Steiner , Achim J.

Subsurface Exploration with the Cone Penetration Testing Truck | USGS Fact Sheet
Evaluation of geotechnical parameters of a lagoonal clay deposit in Jiangsu Lixia River area of China by seismic piezocone tests. Standard practice for classification of soils for engineering purposes Unified Soil Classification System. The cone is advanced downward at a constant velocity of 2 centimeters per second, using hydraulic rams that apply the full ton weight of the CPT truck to push the probe rods to depth.

Evaluation of geotechnical parameters of a lagoonal clay deposit in Jiangsu Lixia River area of China by seismic piezocone tests
Description: Evaluating cyclic liquefaction potential using the cone penetration test. Extensive use is made of the normalized soil behaviour type SBTn chart based on normalized cone resistance Q t and normalized friction ratio F r. Though not designed for continuous coring, the CPT truck can collect discrete soil samples with a piston sampler. Canadian Geotechnical Journal , , 53 9:
