【Abstract】 The test-based design of dam materials is an important item in study on design of an earth-rock dam, which directly determines on both feasibility and economy of an earth-rock dam project. The paper studied the consolidation compression and triaxial shear mechanical characteristics of rockfill material, transition material and cushion material of the concrete face rockfill dam under different porosity conditions, analyzed the impacts of specimen porosity on consolidation deformation characteristics, triaxial shear stress strain characteristics and Duncan-Chang EB model parameters of the dam material and properly evaluated the engineering characteristics of the limestone material of the Gushui concrete face rockfill dam based on the mechanical characteristics test of limestone material of the Gushhui concrete face rockfill dam. The mechanical characteristic indicators meet the design requirement of the concrete face rockfill dam of the Gushui Hydropower Plant.更多还原
