| description | Multichannel Analysis of Surface Wave survey has been conducted to
investigate geotechnical properties in 3 location. They are location 1 in Ledok
Formation, location 2 in Lidah Formation and location 3 in Lidah Formation.
The acquisition use 5 kg of sledgehammer as seismic source with iron plate as an
anvil. Twenty four channel of geophones is used as receivers and digital seismic
data logger as recorder.
Collected data is analyzed by SeisImager/SW software. Geometrical
correction is applied to shot gather data based on configuration in field data
acquisition. To convert data in time-offset domain to frequency-wavenumber
domain we used f-k transformation. The next step is picking velocity in Rayleigh
wave fundamental mode to get dispersion curve. This dispersion curve is inverted
to get 1-D �� profile as function of depth.
Based on this survey, seismic site characteristic of each survey location
can be evaluated based on �� values. Location 1 with dominant lithology is
glauconite sandstone, have result �� values < 180 m/s (soft soil) at depth 0-8 m,
180 < �� < 360 m/s (stiff soil) at depth 8-17 m and 360-658 m/s (very dense soil)
at depth 17-30 m. Location 2 with dominant lithology is napal, have result ��
values < 180 m/s at depth 0-9 m, 180 < �� < 360 m/s at depth 9-17 m and 360 <
�� < 658 m/s at depth 17-30 m. Location 3 in Lidah Formation with dominant
lithology is claystone, have result �� values < 180 m/s at depth 0-12 m and 180 <
�� < 336 m/s at depth 12-30 m. |
