INVESTIGASI NILAI PERMEABILITAS TANAH BERDASARKAN NILAI HASIL CPTU
Abstract: The objective of
this research is to interpret the correlation of CPTu with value of
permeability (k). From the result of CPTu’s data can be evaluated and interpreted
as correlation of value of soil permeability, coefficient of consolidation (ch)
that based on the method on which suggested by Robertson et al (1992b). Profile
interpretation in soil layer was principle performed by Robertson (1986), using
the data value of cone resistance (qc), soil friction along a side sleeve (fs),
and pore water pressure (u2). Those values was firstly calculated to obtain 3
derived units as total cone resistance (qt), friction ratio (FR), pore pressure
parameter (Bq).Value of soil permeability could be estimated from the equation that recommended
by Baligh and Levadox (1986). The result of the test in CPTu-01 area was
performed along the depth 18,44 m from soil surface. Pore water pressure could
be red into 1,4 m, it showed as water surface. while dissipation test was
performed 13,86 m in depth, from soil surface, CPTu-02 was perfomed along the
depth 18,76 m from soil surface. Pore pressure could be red in beginning of the
test, while dissipation test was performed along 10,91 m and 16,75m in depth,
and CPTU-03 was performed along the depth 19,3 m from soil surface
