references for use of a t-probe?
(OP)
Does anybody know if there been any papers or studies done involving a t-probe (long metal rod with a handle)? I wanted to find some definitive documentation on penetration depths, and couldn't find any literature on the web. It seems obvious that applying the weight of your body a point load would help determine the strength strength of a soil. Any ideas?





RE: references for use of a t-probe?
For quantitative results it would be preferable to use a 'mac' probe or similar where you have a known weight falling vertically a known drop height and the penetration is measured and resistance/relative density calculated. See BS5930:1999, BS1377-9:1990 or ISSMFE(53)
Good luck

I commonly use a "T" probe for a rough estimate of the compaction. The T probes that my co-workers and I use are simply pushed in by hand until refusal is met. We stricly use it for spot checking backfill procdures. Typically I can not push probe in more than one to two inches if compaction requirements are being met. If the soil has softened or is loose then I will be able to push the probe all the way. Regardless of how far the probe penetrates I will still have a technician do a density test (nuclear, ballon or sand cone) as the probe is only a very general indication of density. Unless there is more advanced probe than the one I use I would only use this procedure for rough spot checks of the soil.
Hope this helps
