| 摘 要： | 该文在综合考虑挤压式边墙、面板、坝体相互作用的基础上开发了面板堆石坝面板温度应力的数值模拟方法并验证了其合理有效性,然后重点分析了挤压式边墙这种结构对于面板堆石坝面板温度应力的影响规律.分别采用沈珠江双屈服面弹塑性模型和清华弹塑性损伤模型描述堆石料和土与结构接触面,结合三维有限元分析方法计算了设置挤压式边墙以及面板与挤...

| Abstract: | The interaction between the extrusion wall and face slab and a dam body itself is considered to develop a numerical method for the temperature stress of the face slab of CFRD and verify its rationality.The influence of the extrusion wall on the temperature wall of the face slab is then emphatically analyzed.The behaviors of the rockfill and soil-structure interface were described by Shen's two-yield surfaces model and Tsinghua's elasto-plasticity damage model,respectively.The 3D FEM analysis shows the tempe... |
