Abstract  The strength and deformation characteristics of the soil-gravel mixtures must be studied for disaster prevention and to improve safety. Serialized plain strain tests are conducted on various soil-gravel mixtures with aluminum bars used to simulate the gravel. The tests show that the gravel content and gravel shape significantly affect the strength and deformation of the soil-gravel mixtures. The peak strength and dilatancy characteristics increase as the gravel content increases and the gravel becomes more psephitic. Measurements of the gravel movement show that the gravel impedes the formation and development of the shear band by providing a rolling resistance which increases the peak strength.
Keywords soil-gravel mixtures      plain strain test      strength      dilation
