Italian term or phrase: pressione verticale efficace in sito
Grandezza calcolata per stabilire la resistenza di un terreno:
"
L’individuazione del grado di addensamento può effettuarsi mediante la misurazione della resistenza penetrometrica in sito, con rilievo della resistenza Standard Penetration Test (SPT), oppure della resistenza alla punta qc rilevata da una prova Cone Penetration Test (CPT).
La densità relativa dipende dalla pressione di confinamento cui il terreno è sottoposto.
Se un campione sabbioso (appartenente alla categoria dei terreni non coesivi quindi detti appunto terreni incoerenti) viene collocato all’interno di un contenitore, il terreno è in grado di sopportare un certo carico che dipende dalla efficacia del confinamento.

In sostanza, il campione sarà in grado di sopportare un carico P e conseguente tensione σ la cui entità dipende dalla tensione di confinamento disponibile.
Stimando la pressione verticale efficace in sito (pressione tra i grani) e misurando, ad esempio, la resistenza SPT attraverso i numero di colpi richiesto per l’avanzamento del campionatore di 30 cm, si può individuare il valore della densità relativa mediante l’uso di opportuni grafici preparati a tale scopo."

English translation:vertical effective overburden pressure/stress
Explanation:
Overburden pressure, also called lithostatic pressure or vertical stress, is the pressure or stress imposed on a layer of soil or rock by the weight of overlying material.

effective overburden stress = s’vo
vertical total stress = svo
