The objective of this study is to characterize the soft
clay of the BR 101 Highway in Santa Catarina, based on
field and laboratory tests. Field tests consisted of vane
test (VST), flat dilatometer test (DMT) and piezocone
(CPTU). The experimental laboratory program included
characterization, consolidation and consolidated undrained
triaxial tests (CIU). The soil has been characterized as
fluviomarine soft clay, highly plastic, presenting
light to dark grey color, and low to medium sensibility.
The material has shown high compression rate and low
resistance. The laboratory tests have complemented the
field investigation. Similar constrained modulus (M) values
were obtained both from the dilatometer test and from the
conventional consolidation test. Therefore, DMT showed to
be a suitable test for settlement estimation. Cone factor
(NKT) shall be carefully estimated due to its influence in
the determination of the undrained shear strength (Su).
Field and CIU tests performed in the soft clay deposits
presented values between 10 and 25kPa. Emphasis is given in
the importance of the field tests to determine the
geothecnical parameters of the soft clay, due to their
quick and easy performance.
