| 摘 要： | 动力分析中分段迭代并分段改变基同计算方法是对计算程序的新发展，堆石、垫层、接触面部是用该坝设计中采用的石料作大型振三维试验、振动拖板、大型振动单剪试验求得的参数，计算得到的绝对加速度、动位移、面板动挠度、动应力、接缝动拉压剪量都颇合理，面板接缝的静动压量计算值可作为止水结构设计的依据。在地震过程中能满足抗滑稳定的要求，不必采取其他加固措施。

| Abstract: | In this paper,Tiansheng Qiao-I concret-face rockfill dam (CFRD)is analysed in detail by three-dimensional non-linear FEM The calculation method of sectional iteration and sectional changing found-frequency is a new development of the dynamic calculation in non-linear FEM The parameters of rockfill, pad and interface between faces are obtained from preliminary design which has been achieved from large type dynamic triaxial test, large type dynamic simple shear test and tractive plate test The results of computation for absolute-acceleration, dynamic displacement, face dynamic deformation,dynamic stress and dynamic tension, compression and shear value of joint seam are resonable The value of dynamic tension, compression and shear of joint seam can be used as the foundation for hydraulic structure design Since the concrete-face can meet the requirement for stability against sliding, no more reinforcement is recommended |
