The use of neural networks for the prediction of cone penetration resistance of silty sands

“…The advantages of CPT tests are: (1) fast and continuous profiling, (2) repeatable and reliable data (not operator-dependent), (3) economical and productive, and (4) strong theoretical basis for interpretation [2]. The disadvantages of CPT tests are: (1) relatively high capital investment, (2) requiring skilled operators, (3) no soil sample, during a CPT, and (4) penetration that can be restricted in gravel/cemented layers [2]. The CPT measures the cone penetration resistance and the sleeve friction resistance.…”

“…The piezocone penetration test (CPTu) measures additional parameter that is the pore water pressure. These measurements can be effectively used for the following applications: (1) to classify soil identification, (2) to directly estimate pile capacity from the CPTu, (3) to evaluate soil properties through an appropriate correlation, especially the undrained shear strength, (4) to determine bearing capacity and settlement of the shallow foundations, (5) to control compaction in ground improvement, (6) to design wick or sand drains, and (7) to evaluate the soil liquefaction [2]. Therefore, the CPTu can be used for a wide range of geotechnical engineering applications [1].…”

“…Currently, among these methods, the cone penetration test (CPT) is considered one of the most useful in situ tests and is widely used in onshore and offshore soil investigations [1].

“…Several in situ tests, namely the standard penetration test (SPT), cone penetration test (CPT), flat dilatometer test (DMT), pressuremeter test (PMT), and vane shear test (VST), have been commonly used to obtain the engineering parameters of the soils in the subsurface needed for geotechnical design [1]. Currently, among these methods, the cone penetration test (CPT) is considered one of the most useful in situ tests and is widely used in onshore and offshore soil investigations [1].…”
