Mechanical Properties of Roller Compacted Concrete under Triaxial Stress State
Considering the true mechanical states of roller compacted gravity and arch dams, the strength experiments of the roller compacted concrete (RCC) specimens with two graded-aggregates made from a high arch dam are carried out. These specimens are of three kinds: body specimens, layer-treated specimens and layer-untreated specimens and the tests include direct shear and triaxial compressive-compressive-shear, tensile-compressive-shear tests. The shear strength of three kinds of specimens under different stress states is analyzed systematically. By regression of the tests results, respective failure criterions for RCC under different combined loads are proposed.
