The aim of the present paper is to study the behavior and relations of soil properties by using statistical analysis of cluster and factor analysis. This was achieved through the simulation of soil profiles and properties to a depth up to 15m at 30 different locations by using cluster and factor analysis R-mood by considering WARD method. The present paper involved the investigation of engineering, physical and chemical properties of the soil by comparing two types of soil, soft (subsidence) and normal (no subsidence) soil. The cluster analysis (R-mode) shows two main groups. First group-A- represents the stiffness of the soil, while group-B, was divided into two subgroups, B1 and B2. Subgroup-1 represents the saturation and moisture of soil and it is the effect on soil strength, and B2 consists of variables that affect soil stiffness and lead to weak soil. The factor analysis indicates that there are three factors. The first factor, affects about 38.4% of the total effect, which represents the weakness of soil and chemical properties. The second factor contributed to 28.3% and consists of internal friction and shrinkage. The third factor contributes to 20.2% which represents the losing of water and consolidation of clayey soil
