| 中文摘要: |
| 针对面板堆石坝工程中软岩堆石材料的利用问题，采用数值计算分析的方法，结合具体工程的计算实例，分析了利用软岩堆石料的面板堆石坝的应力变形特性。在此基础上，研究了软岩堆石料的分区布置问题，进而提出了面板堆石坝软岩堆石料利用的基本原则。研究结果表明：在利用软岩修筑的面板堆石坝设计中，通过合理布置软岩材料分区，可以在保证坝体整体稳定和面板受力均匀的前提下，尽可能地扩大软岩利用区的范围，使工程设计进一步得到优化。 |

| The deformation characteristic of three CFRD constructed with soft rock is analyzed by means of numerical computation.According to the computation result,the optimization of zoning for soft rock is studied.On this basis,the principle of utilizing soft rock to construct CFRD is suggested.It is concluded that soft rock can be utilized to construct CFRD and the extent of utilization can be extended to a very wide range if the zoning of soft rock is optimizd,in case the stability of the dam is ensured and the stress condition of concrete slab is in good situation. |
