Concrete face rockfill dam is a special kind of dam.It is one of the main dam embankment dam hasstrong adaptability, topography, geology, climate and other conditions, it has been widely used in the damconstruction industry and research, but also the water conservancy and hydropower project to promote oneof the three new dam. To do a more in-depth study of the deformation characteristics of concrete facerockfill dam, the main contents are as follows:(1) Analysis of rockfill deformation and deformation of the front influencing factors, discussed therole of these factors under different deformation characteristics, the construction of the engineeringproperties of rockfill materials, load and valley shape deformation of rockfill explore the effect of thedeformation characteristics of rockfill under the role of these factors and rockfill material constitutivemodel, strength and failure criterion. Compare the settlement of the construction period and after thecompletion of the settlement, showing the distribution of the settlement after the impoundment dammodulus of deformation at different times presented are different.(2)Analysis of concrete face rockfill dam Mechanical properties and deformation of the dam, and toexplore the deformation characteristics of the panel in the role of these factors.(3)By simulating a concrete face rockfill dam dam in different conditions of stress and deformationnumerical analysis, in-depth study Deformation of the upper dam, and the dam panel overlay, toe board, theconnecting plate stress and deformation between the cut-off wall, the structure and design of the project forfurther argument. Three-dimensional combination has been built rockfill dam settlement deformation lawand domestic J Engineering of rockfill indoor large triaxial rheological test data, a description of rockfilllong-term deformation rheological model, and applied to the J engineering concrete face rockfill dam finiteelement analysis.
