Abstract
An earth pressure acting on quay wall structures can be reduced if a tire chip is used for the backfill. But, it is a problem that tire chips have high compressibility and it is easy to deform. To prevent this problem, tire chips are considered to be used with mixing with sand. In this paper, a series of triaxial compression tests of rubber sphere specimen was conducted, and investigations of its shear strength and compressibility of rubber sphere specimen and deformation of rubber sphere particles were conducted with X ray CT scanning. Relationship between shear strength characteristics and change of internal structure and deformation of the particles were discussed.
