Descripción
Pressiometric Method The pressiometric tests (PMT) are loading tests carried out by installing a dilatable cylindrical probe at a given depth in the soil, gradually expanding it and measuring pressures and deformations simultaneously. The net ultimate bearing capacity is determined by the following formula:
Qnet=Kppleiβ*iδ
Where:
kp: pressiometric bearing factor; ple*: equivalent net ultimate pressure; iδ: load inclination reduction coefficient; iβ: slope inclination reduction coefficient.
Static Penetrometer Method The static penetrometer method uses the values of resistance at the tip of a static penetrometer. The net ultimate bearing capacity is determined by the following formula:
Qnet=Kcqceiβ*iδ
Where:
kp: penetrometer bearing factor; qce: equivalent tip resistance; iδ: load inclination reduction coefficient; iβ: slope inclination reduction coefficient.
For both methods, the design resistance follows the guidelines of Eurocode 7 (NF P94-261).
