| 摘 要： | 在土石坝设计中,材料渗透参数的选取是坝体防渗设计的重要部分,它对坝的渗透稳定起着至关重要的作用.考虑非饱和区的影响,在材料各向异性的情况下,分别对其进行渗流计算分析,计算结果表明:在非饱和区的存在和材料渗透参数的各向异性的条件下,单宽流量明显增大;非稳定渗流下,自由面变化显著.

| Abstract: | In designing the earth-rock dam with core wall,the selection of hydraulic conductivity of impermeable part for anti-seepage of dam.is an important work in anti-seepage design.Taking the actual situation of a project as a background,under the condition of anisotropic materials and effect of unsaturated zone,the seepage calculations are carried out to discuss the distribution of seepage field.The results show that the increases in the unit discharge and the changes of phreatic lines are obvious under conditio... |
