面板堆石坝接缝中铜片止水的抗剪能力是铜止水发挥作用的关键,本文以铜片的抗剪试验为依据,采用弹塑性大变形有限元数值分析方法对铜片结构各部位的尺寸对铜片抗剪能力的影响程度进行了考查,为铜片的设计提供了比较全面的有实际意义的建议,弥补了单纯采用试验方法研究铜片抗剪能力在系统和深度方面的不足
The shear resistance of copper diaphragm in the seams of CFRD dam is the key to the effectiveness of copper stop water. In this paper, based on the shear test of copper plates, the elastic-plastic deformation finite element method The size of the parts of the copper shear strength of the extent of the impact were examined for the design of copper provides a more comprehensive and practical recommendations to make up for the pure use of experimental methods to study the shear capacity of copper in the system and depth insufficient
