摘要
碾压混凝土坝采用分层碾压工艺,一般认为层面之间是薄弱部位,为坝体强渗透层。在碾压混凝土坝体渗流有限元分析中,用无厚度的接触界面单元来模拟分析碾压混凝土层面的渗透作用,可以不增加单元剖分的工作量而有效地模拟薄弱层面的渗透影响。
The technology of stratified rolling compaction is employed for RCC. Intensively percolating areas in the mass of dam are generally the weaker parts between layers. In finite element analysis for percolation in the dam, action of bedding seepage in RCC dam is simulated and analized by interface elements without thickness, which can effectively simulate the influences of percolation in weaker bedding surfaces without adding working volume for element subdivision.
