| Summary: | The development of tunnels is currently a relevant transportation option. To
understand subsurface conditions and determine tunnel locations, this research
utilized geoelectric methods such as Electrical Resistivity Tomography (ERT), Vertical
Electrical Sounding (VES), and borehole data. Four ERT survey lines, each
approximately 440 meters in length with electrode spacing of around 10 meters, were
conducted. The survey configurations employed included the Wenner-Schlumberger
and Dipole-Dipole methods. The findings of this study revealed that the subsurface
lithology consists of high-resistivity soil (>33.2 ?m) with a thickness of up to 40
meters. Wet clay layers exhibited low resistivity (<5 ?m), while weathered clay showed
moderate resistivity values (5-33 ?m). The results from the ERT geophysical
investigation, in conjunction with geotechnical data, can be utilized to determine the
optimal location for the high-speed train tunnel between Jakarta to Bandung. The
recommended tunnel location lies within the clay and mudstone layers, characterized
by moderate to high resistivity values. In summary, this research employed various
geoelectric methods to assess subsurface conditions and identified an ideal tunnel
location within the moderate to high-resistivity clay and mudstone layers |
