Evaluation of Soil Swelling and Liquefaction Potential Using a GIS Software: a Case Study of Tabriz, Iran

Worldwide research on inflation and soil liquefaction is in nowadays a hot cake. Critical issues on soil liquefaction can cause irreparable effects to surface and undersurface installation the results which could be easily realized through the accidents like, derailment of rail, distortion in the roads, bend building, damage to the pipelines and an even close cross-section of the tunnel and reversal structures. Thus maintaining some specific patterns is always felt necessary to identify such points to avoid these destructive phenomena, and the structures would remain safe in coming future from vulnerabilities of hazards. We aimed this study to forward some guidance to identify and modifies regions having critical issues relating to the high liquefaction. From 50 excavated bores, total standard influence numbers and the Atterberg limits at different depth have been calculated. Further, by using of Arc GIS application, geostatistics analysis tool and by using of interpolation Kriging method, zoning maps of liquefaction and critical situation have been estimated. The obtained results hope to be useful in future plans to decrease the relevant accidents.
