Question about super heavy dynamic penetration - hapsea - 12-08-2010 Dear members, I have a device like the one in the picture attached. LMSR-vk is able to perform the following DCP methods: 1. DPL (dynamic probing light) 10 kg / 50 cm 2. DPM (dynamic probing medium) 30 kg / 50 cm 3. DPH (dynamic probing heavy) 50 kg / 50 cm 4. DPSH-A (dynamic probing super heavy) 63,5 kg / 50 cm. 5. DPSH-B (dynamic probing super heavy) 63,5 kg / 75 cm. Curently i am using the DPSH-B with readings of N at every 20cm (N20) I am interesting in using the program NOVOSPT. For that i have to convert the N20 in N60 . Can anyoane help me in this problem? A book or a code will be very appreciated. thank you in advance RE: Question about super heavy dynamic penetration - avscorreia - 12-08-2010 Hi. From my experience, the correlation between DPSH tests and SPT depends largely on the local conditions, so what we usually do is the following: - establish a preliminary geotechnical investigation programme with a couple of SPT's and DPSH's in the same locations; - establish correlations between DPSH and SPT with sufficient reliability; - use the DPSH to refine the mesh of the site investigation. Hope it helped. Best regards.
