- Abstract:
- :GASCO site has been evaluated on the basis of site investigation,seismic activity and seismic hazard assessment.Shallow seismic refraction survey has been carried out to estimate the elastic and dynamic constants for soil and rock materials throughout 8 seismic profiles.The ground model at the site consisting of two layers characterized by moderate to high values of elastic and dynamic constants indicates that the site has good soil and foundation rock.Both historical and instrumental earthquakes in a circle with radius of 150 km around the proposed site were collected and precisely analyzed.The site is affected by four seismic source zones:Central Gulf of Suez,Cairo-Suez District,Southwest Cairo and Beni-Suef,based on the tectonic setting,the seismicity,geological structures and fault plane solutions of major earthquakes.Maximum earthquake moment magnitudes(MW)have been identified for these source zones using seismicity statistics together with expert judgment.In addition,the stochastic approach was applied for the seismic hazard assessment in terms of Peak Ground Acceleration(PGA)and response spectra.It is noticed that Beni-Suef is the nearest source to the site and the maximum PGA value produced from this seismic source reaches 9.34 cm/s2.This value is small and reflects that there is no hazardous effect to be expected at GASCO site, which indicates its validity for civil engineering purposes.The response spectra at 1%,3%,5% and 10% damped Pseudo-acceleration(PSA)were also simulated at the GASCO site.
