| Summary: | Infrastructure development into peat
necessitates geotechnical engineers to find a better
profiling method. The conventional profiling carried
out by either a localized peat augering or a borehole
drilling is often subjective, lacking of details, time
consuming and high cost. This paper presents results
and analysis of in-situ tests that combines Electrical
Resistivity Tomography (ERT) and Multichannel
Analysis of Surface Wave (MASW) methods.
The results show that ERT method is a good tool for
delineating the boundary between peat and underlying
mineral soil using their large contrast in electrical
resistivity values. The ERT enables the peat thickness
to be determined accurately, but lacks of information
regarding peat mechanical properties. On the other
hand, the MASW provides a lower contrast between
the peat and the mineral soil layers compared to
the ERT, but it can provide the mechanical properties
of the two layers based on shear wave velocity measurements. Hence, the combination of these two
methods were found to be improving the peat profiling
for engineering application. The results correlate
well with the existing peat auger and borehole
records in the study area. The combined ERT and
MASW methods is recommended to be practically
used by engineers as the current best solution for peat
profiling. |
