| 摘 要： | 结合一工程实例,基于改进的湿化变形计算模型,采用邓肯-张E-B本构模型和有限元分析方法,研究软岩料的湿化变形对堆石体及面板应力变形的影响。结果表明:由于软岩堆石料湿化变形的影响,坝体整体沉降增加,并发生向下游的水平位移,面板的挠度增大,面板的压应力增量增大,对面板的应力变形产生了不利影响。

| Abstract: | Combined with a project case,based on the improved calculation model for wetting deformation,Duncan-Chang E-B model was adopted to simulate the rockfill embankment.This paper studied the effects of wetting deformations upon rock-fill and face slab of CFRD.The research results indicated that the effect of rockfill material wetting deformations made the dam embankment settlement increases,and the increment of face slab pressure stress was so large that an unfavorable effect upon the face slab stress deformation was generated. |

| Keywords: | soft rock materials wetting deformation initial strain finite element method(FEM) |
