Finite Element Analysis Of Xi Liu Shui Face Rockfill Dam

It is well known that the modern concrete face rockfill dams (CFRD) have so many advantages such as small amount of dam body, short construction period and low project cost that recent years witness a great development of CFRD in China. However, the construction of CFRD is guided more by experiences than theories, therefore, much efforts is needed in the theory study of CFRD in which one of the difficulties is, in the computing and analyzing of CFRD, the existence of a plenty of uncertainty factors. The element analysis is one of the major methods in the calculation of face rockfill dam.The original is consider the norm demand , and unite the relevant concrete embankment research progress condition of home and abroad , and carries on listed below research work to the xi liu shui huge dam embankment part of the body : The representative cut plane rightful mould style , three-dimensional static analysis of finite element and huge dam three dimensions moving force analysis and three-dimensional on the huge dam run the variation unpack and stagnant water the composition mould style and so on .Selecting three representative cuts plane on the huge dam , and carries on the static calculation of two dimension finite element , and distinguishes rightful quality of embankment part of the body composition shape initially , and is underway that the section optimizes , parameter physics mechanics nature is verified is anticipated that by the cut plane along with embankment which supplied work out initially to the designing institute , and physics mechanics nature is verified , and constructs the embankment control parameter to carry on the sensitivity analysis to the building.Basing on the plane finite element analysis , static finite element of three-dimensional ( pellet plastic property ) analysis is carried on , the main substance is : Concrete plankstatic stress , displacement and the bending deflection ; The static stress and displacement distribution of rockfill ; Static displacement of three orientations that slab joint and peripheral joint.The main substance of huge dam composition three-dimensional finite element moving force analysis is : The plank moving stress , displacement and bending deflection ; The moving stress and displacement distribution of rockfill ; Three orientation moving displacement that slab joint and peripheral joint; Evaluating the entire moving force work effect of the structure.
