Abstract


With the concrete face rockfill dam in recent years in China 's construction of an increase in the number of the level of design and construction also will continue to improve , the number of new design and construction methods are emerging , making the CFRD promotion on a higher level , which squeeze type sidewall technology since its introduction in 2000 , because it has to simplify the construction process , provides a solid support for the panel , while increasing diversion flood protection dam security , some engineering applications , but it there are still a lot of problems in theoretical basis and practical construction as a new technology , the need for further argument . This paper to Bajiaohe a rockfill dam , for example , the use of large general-purpose finite element software ANSYS to calculate the three - dimensional stress and deformation of the dam and the panel during the construction phase and the impounding period , analysis of the calculation results and summarizes some of the features in the construction, management , useful conclusions . Concrete faced rockfill a Bajiaohe Reservoir as a water retaining structures , reservoir dam site was \slope reinforcement technology . Calculated part as the main research object to Bajiaohe an extrusion-sidewall face rockfill dam , large finite element software ANSYS and its user-programmable characteristics (UPFs) , secondary development , widely used in rockfill materials Duncan - Zhang model as well as the mid-point increment method and the contact the ANSYS point surface contact elements analog panel with the wall , calculated on the basis of the dam and the panel during construction and impounding period of stress and deformation analysis of extrusion-sidewall on
