CPT vs Unit Weight (correlation)

Written by Gouw Tjie Liong, Ir., M.Eng, ChFC, PhD. Posted in Technical Information

This chart is useful as a preliminary estimate of unit weight.

Robertson, P.K., and Cabal, K.L, 2010, Estimating Soil Unit Weight form CPT, 2nd Int. Sym. On Cone Penetration Testing,, Huntington Beach, CA, USA.

warning:

Be very careful in using correlation! and It might be very useful for a feasibility study of a design; Always do the proper soil test for a real design. It is our job to convince the owner to do a proper soil test.

Kesalahan Menyedihkan!!

Written by Gouw Tjie Liong, Ir., M.Eng, ChFC, PhD. Posted in Note and Discussion

Di bawah ini penulis sajikan beberapa contoh kesalahan FATAL yang penulis jumpai dalam laporan penyelidikan tanah. Yang lebih parah adalah laporan yang salah ini ditanda-tangani oleh orang yang sudah bergelar Master of Geotechnical Engineering dan bahkan ada yang sudah senior. Kiranya perlu sekali diadakan STANDARISASI keahlian dari para teknisi dan penanggung jawab laboratorium-laboratorium penyelidikan tanah kita.
