摘要：For selecting reasonable embedding method of the giant spiral case, contact nonlinear finite element analysis is used to obtain optimal range of cushion laying for the combination embedding method of direct embedding and cushion in Wudongde hydropower station, comparing concrete stress, non-uniform uplifting displacement of baseplates, the bearing ratio of concrete, etc. The optimization results show that the combination scheme with cushion laying to 270°section can meet the control standards of strength, stiffness and displacement for structure, which is the best embedding method for this hydropower station.
