The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils. Based on this history it has also been called the "Dutch cone test". Today, the CPT is one of the most used and accepted soil methods for soil investigation worldwide.

PCT designated stage expiredWO2025111638A1Mechanical depth measurementsMaterial strength using tensile/compressive forcesSoil scienceDrive shaft
The described cone penetrometer system is a geotechnical testing apparatus designed for accurate soil assessment comprising a drive shaft with an attached cone at its distal end, a load cell connected to the shaft for precise measurement of applied force, and a depth transducer to accurately gauge the penetration depth of the cone. This system distinguishes itself from traditional methods by directly converting force to bearing capacity based on the cone's surface area, eliminating the reliance on less accurate blow conversion tables. The inclusion of a reliable depth transducer ensures precise depth measurements, facilitating accurate plotting of bearing capacity against depth. While delivering enhanced accuracy, the system retains the advantages of lightweight, cost-effectiveness, and manual operation, aligning with the simplicity and efficiency characteristic of traditional methods like the Dynamic Cone Penetrometer (DCP) compared to more intricate and expensive Cone Penetration Test (CPT) systems.

Seismic reflection data based in-situ sounding test layout active learning optimization method
This invention belongs to the field of marine geotechnical engineering technology and relates to an active learning optimization method for in-situ cone penetration test layout based on seismic reflection data. First, based on a physically driven deep learning model, using modules such as wavelet inversion, reflection coefficient inversion, and acoustic attenuation compensation, cone tip resistance is gradually predicted from seismic reflection data, achieving high-fidelity extrapolation from sparse one-dimensional in-situ test data to continuous multi-dimensional profiles. Second, the average seismic reflection amplitude is used to quantitatively evaluate stratigraphic complexity, prioritizing the deployment of initial test points at locations with high complexity. In the sequential sampling stage, a two-stage candidate point selection strategy is proposed: an early inter-layer reflection amplitude strategy is used to quickly discover hidden strata, and a prediction uncertainty strategy is used in the later stage to minimize global error. A joint termination criterion combining the moving average convergence criterion and the continuous no-improvement criterion is introduced, stopping sampling when the marginal information gain decreases, avoiding the cost waste or insufficient accuracy caused by empiricism.
