【Abstract】 The existing results in the construction of worldwide earth-rockfill dams were summarized. With regard to the construction of high earth-rockfill dams of hydropower development in West China,many key technical problems of earth-rock materials were emphatically discussed,including the test methods under high stress conditions,the strength deformation properties and constitutive models,the long-term deformation properties,the dynamic properties and constitutive relations as well as the mechanical properties of contact faces between soils and structures. On such a basis,the research interests and the main scientific problems in the future were discussed based on the above analyses.更多还原
