Geotehnično preiskovanje in preskušanje - Preskušanje na terenu – 2. del: Dinamični penetracijski preskus

Ta dokument določa zahteve za posredno preiskovanje prsti z dinamičnim penetracijskim poskusom kot delom storitev geotehničnega preiskovanja v skladu s standardoma prEN 1997-1 in prEN 1997-2. Ta dokument zajema določevanje odpornosti prsti in mehkih kamnin na dinamično penetracijo konusa na kraju samem. Za zabijanje konusa se uporabi kladivo z določeno maso in višino padca. Penetracijski odpor je določen kot število udarcev, ki so potrebni, da konus prodre do določene globine. Podatki o globini se neprekinjeno zapisujejo, vendar brez zbiranja vzorcev.
Vključeni so štirje postopki, ki zajemajo številna posebna dela na udarec:
– lahek dinamični penetracijski poskus (DPL): preskus, ki predstavlja dinamično opremo v spodnjem delu masnega razpona;
– srednji dinamični penetracijski poskus (DPM): preskus, ki predstavlja srednje težko dinamično opremo;
– težek dinamični penetracijski poskus (DPH): preskus, ki predstavlja srednje do zelo težko dinamično opremo;
– zelo težek dinamični penetracijski poskus (DPSH): preskus, ki predstavlja dinamično opremo v zgornjem delu masnega razpona.
Rezultati preskusa iz tega dokumenta so zlasti ustrezni za kvalitativno določevanje talnega profila skupaj z neposrednimi raziskavami (npr. vzorčenje v skladu s standardom prEN ISO 22475-1) ali kot relativna primerjava drugih preskusov na kraju samem. Uporabijo se lahko tudi za določevanje trdnostnih in deformacijskih lastnosti prsti, običajno nekohezivnega tipa, z ustreznimi korelacijami pa jih je mogoče uporabiti tudi za drobnozrnate prsti. Rezultati se lahko uporabijo tudi za določevanje globine zelo zbitih slojev zemljine npr. da se določi dolžina nosilnih pilotov in odkrijejo zelo rahle, luknjaste, ponovno nasute ali nasute zemljine.
