Geotechnical site Characterization for Vijayawada UrbanAuthors: akhila.m@research.iiit.ac.in ,Neelima Satyam Conference: 3rd Indian Young Geotechnical Engineers Conference (3IYGEC 2011) Date: 2011-03-25 Report no: IIIT/TR/2011/82 AbstractGeographical statistics of India show that almost 54% of the land is vulnerable to earthquakes, which insists on the immediate call for the Seismic Hazard Anlaysis of different regions of the country. Even though the zoning of the country has been done it offers a very vague idea of the earthquake hazard in any particular region due to the lack of database in India with regard to the earthquakes prior to historical period.Geotechnical Site Characterisation is an important task in the Seismic Hazard Analysis for finding out the soil startification. In this paper, the region of interest is Vijayawada city which falls in zone III according to IS 1893: 2002. It is the 34th largest town in India (population wise), and the 3rd largest town in Andhra Pradesh. Using the borehole data collected, soil profiles and the grain size distribution curves have been developed. The predmominant soil in all the Northern, Eastern, Western and Southern parts of the city have been found out.Using this data, the locations that may be prone to liquefaction are also identified.
