Abstract

Abstract

In order to study the deformation performance and damage development of pebble concrete under triaxial compression, based on the parameters of confining pressure, 27 Φ100×200 cylinder specimens were designed and tested under triaxial compression.The results showed that the failure patterns of the specimens under triaxial compression were divided into vertical splitting failure, oblique shear failure and transverse rupture failure according to different confined pressures. As the confining pressure increased, the peak of the stress-strain curve of specimens increased, the descending section of the stress-strain curve gradually flattened, and the energy dissipation increased. The confining pressure could significantly improve the ductility of pebble concrete and restrain the damage development of pebble concrete. Finally, the functional relations between the lateral confining pressure and the actual energy dissipation was presented by fitting the experimental data.
