dc.description.abstract | MASW or Multichannel Analysis of Surface Wave is a seismic method that utilizes the
dispersive property of surface wave to interpret surface wave velocity which is directly related
to the stiffness of a subsurface layer reaching 30 meters depth that beneficial in the
geoengineering field. The goal of this research is to interpret shear wave velocity of subsurface
layer in an area to inform the stiffness level of - subsurface layer through shear wave velocity
and depth profiling. The steps of this research are converting seismic raw data into numeric
data, generating dispersion image, extracting dispersion curve from dispersion image and
analyzing dispersion curve by theoretical and experimental data.
Based on analysis results, shear wave velocity obtained up to 170m/s with 16 meters
investigation depth. Whereas fundamental mode frequency of Rayleigh wave between 2 – 12
Hz. Low shear wave velocity (<180 m/s) of investigated area indicates that the subsurface layer
dominated with soft soil which is an early sediment in the shape of alluvium layer and has high
seismic wave amplification that hazardous for building build upon the layer. | en_US |
