| 摘 要： | 在切向水流-土体渗流相互作用试验基础上,结合Fluent软件数值模拟,对比验证和分析了切向水流-土体渗流相互作用规律和内在机理.结果表明,数值模拟与试验结果吻合良好,切向水流对土体渗流的影响明显;切向水流条件不变时,渗流通道出口的压力场与流态随着渗流速度的变化而改变,且渗流速度越大,土体透水系数越大.

| Abstract: | Based on experimental results and simulations with software Fluent,the interactions between seepage and tangential flow were investigated,and the results of experiments and simulations agreed well.Results show that the flow obviously affects the seepage in the sand soil.For the same tangential flow,the pressure fields and streamlines change with the seepage velocity,and the seepage conductivity increases with the increasing seepage velocity. |

| Keywords: | seepage tangential flow interaction mechanism |
