Research Abstract	Unusual soil l is the soil which became the problem that the handling is difficult in design construction. Moreover, unusual soil foundation often causes extensive ground damage which cannot predict by the normal construction management. Recent years, many important infrastructures are constructed on an artificial reclaimed foundation filled up with unusual soils and intermediate soils. Therefore, it is very important to comprehend the mechanical behavior of unusual soils properly and make use for adequately design construction. In this research, various laboratory experiments were conducted using unusual soils and intermediate soils for the purpose of understanding and interpreting its mechanical behavior based on a soil skeleton structure concept.
