dc.description.abstract	The research is mainly determining the degree of expansiveness and shrinkage swell characteristics of soils in some areas of Amhara region. Accordingly, several data were taken from design office and from theses that were done before on different local places. Relations obtained from statistical analysis between the index properties, and swelling pressure with index properties of expansive soil. Equations were developed, by taking one or more of the soil property parameters (Liquid limit, plastic limit, shrinkage limit, moisture content, dry density and plastic index) in different combinations. Based on the experimental results obtained from different theses, correlations and empirical equations have been developed. The multiple regression Analysis indicates that there is a relationship between index properties and swelling characteristics of expansive soils in some areas of the region. The developed equations could be used for estimation of swelling characteristic of the soils in the study areas. The suggested equations used for the estimation of the swelling pressure of the areas are the equations with higher coefficient of estimation. Five equations have been selected to predict the swelling pressure of soils of the region. From such equations (Eqn. 3) more preferable than the others due to R2=0.999, MSE (error) =0.0037 In addition evaluation of one point liquid limit test has been checked for expansive soils of Amhara region. Accordingly, several data were taken from different theses that were done before. The relations obtained from statistical analysis have R2 of 0.83	en_US
