Since its invention in early 1980’s, seismic cone (SCPTu) has become one of the most advanced tools for
in-situ geotechnical investigations or for determining soil properties at small to large strain levels. SCPTu
combines the advantages of piezocone (CPTu) with seismic wave measurements for direct determination
of consolidation, shear strength and stiffness properties of soil. Compared with other in-situ tests, SCPTu
is high in both accuracy and efficiency. It is most suitable for soil profiling or site characterization for
reclaimed land or soft to very stiff soil. In this seminar, the principles and testing procedures of SCPTu
tests will be explained. A few local case studies will be provided to illustrate the necessity and importance
for such type of tests in Singapore and the typical results. Data interpretations and the other potential
applications of SCPTu will be introduced. Participants to this seminar will have a much better
understanding on how and when to use SCPTu for geotechnical projects.
