Investigation of dynamically compacted ground by HVSR-based approach

Soil Dynamics and Earthquake Engineering, 2013
Abstract This paper proposes a HVSR (horizontal to vertical spectral ratio)-based approach to assess a deep and dynamically compacted fill area in Western Sydney. In addition to recognizing that the predominant resonance peak of the HVSR curve is a reflection of the impedance contrast between the surface layers and bedrock, the present paper ...

Centroid-based Cluster Analysis of HVSR Data for Seismic Microzonation

Proceedings, 2014
atasets acquired for studies of seismic microzoning in various urban centers of Sicilian towns, have been used to test clustering analysis through a non-hierarchical centroid-based algorithm. In this context clustering techniques may be useful to identify areas with similar seismic behaviour through HVSR data.

Ambient micro-vibration measurements in geotechnical engineering: a practical approach to the HVSR method

Depuis les dix dernières années, la communauté géotechnique s’intéresse de plus en plus à une technique géophysique basée sur l'analyse du bruit ambiant enregistré à l’aide d’un sismomètre à trois composantes à la surface du sol.

Correlation Between Building Damage Levels and Microtremor HVSR Curve Parameters

Frontier Advances in Applied Science and Engineering
The level of damage caused by an earthquake is related to the physical parameters obtained from Horizontal-to-Vertical Spectral Ratio (HVSR) analysis. The dominant frequency (f0) and wave velocity are the two HVSR parameters used.

Site Characterization and Shallow Shear Velocity through HVSR Measurements around the Hyderabad Metropolitan Region, India

Journal of the Geological Society of India
We investigate the site characterization and shallow shear velocity profiles from the analysis of the Horizontal to Vertical Spectral ratio (HVSR) around the Hyderabad metropolitan region (HMR), which falls under the southern Indian shield.

Landslide Surface Prediction with Combined HVSR and VES Geophysical Techniques: Case Study in Semarang City, Indonesia

International Journal of Hydrological and Environmental for Sustainability
. There are settlements in Tambakaji, Semarang City, which are threatened with landslides because they are located right at the foot of the slope, so research is needed to determine the potential for landslides on the slope.

SESIMIC SITE CHARACTERIZATION BY HVSR APPROACH

The surface seismic methods represent non-invasive, widely accepted geophysical methods for near-surface characterization and evaluation of the local soil conditions which have significant influence on the site response during an earthquake. In this study particular attention was paid to the use of the single station microtremor Horizontal-to-Vertical

Combined Analysis of Ambient Vibration HVSR and Active MASW Method

Proceedings, 2014
The well-known non-uniqueness inversion problems of dispersion curves as well as the reduced resolution at higher depths could be improved by performing a combined analysis of data sets of different types. In this study, Nakamura’s technique or HVSR technique was applied to several ambient vibration recordings performed at the surface of alluvium ...
