چکیده

With an ever-increasing population growth, the development of industries and the deficit problem of land for establishing the required constructions have been caused that people use the lands with lower engineering qualification. But for establishing a suitable construction the qualification of soil should be improved by a technique respect to engineering parameters. In this condition it has a suitable operation in effect of involving forces. Soil improvement techniques can be classified in different points of view. These methods are divided in to three general groups: Compaction, Solidification and Stabilization. With regard to this point that coastal soils have the capability of liquefaction and they are clayey soils, in this article, first of all we will inspect these soils and the problems that they are caused and then their characteristics improvement techniques based on geotechnical methods such as placing trenches for limited land, sand wills for liquefiable, saturated and clayey soil ;stone columns for clayey soil that have bearing capacity problem and dual purpose micro pile and compaction will be surveyed. Outdoor investigations and their findings show that the soils with SPT lower than 12 in each depth are problematic surely and should improved.
