| 摘 要： | 水闸闸基渗流和两岸的绕渗形成较为复杂的三维渗流场。采用固定网格结点虚流量法结合改进排水子结构有限元求解技术,对平原地区一大型水闸进行三维渗流场计算分析,着重研究了混凝土铺盖和混凝土地下连续墙的防渗作用及其对闸基渗流场和两岸绕渗的影响。此外,针对闸基特殊地层分布的情况,提出了相应的优化渗控措施。

| Abstract: | The foundation seepage and bypass seepage form a complicated 3D seepage field in sluice. The numerical procedure of nodal virtual flux for fixed mesh combined with improved technique of drainage substructure is applied to solve the 3D seepage field of a sluice in plain area. The anti-seepage function of concrete blanket and underground continuous concrete cutoff wall is studied emphatically and the influence on the bypass seepage is also investigated. Besides, the optimized anti-seepage logout is put forward based on the analysis of seepage field of layered foundation. |
