百色水利枢纽地下厂房区渗流场三维有限元分析

采用固定网格求解有自由面渗流问题的结点虚流量法和排水孔改进排水结构技术，精细模拟了排水孔、幕中众多排水孔的孔径、孔距、孔深及排水降压渗流行为，自动判别排水孔是否穿越渗流自由面，对百色水利枢纽地下厂房（地面升压站方案）的渗流场进行了详细的计算分析，并对厂区渗控设计方案提出了评价和建议。

Three-dimensional FEM Analysis on the Seepage Field of Underground Powerhouse Area for Baise Hydroproject

Based on the method of nodal virtual seepage flux and the technique of improved drainage substructure, this paper simulate curiously the diameter,distance,depth of draining relief holes or draining relief curtains and estimate if draining relief holes are across seepage free surface.And the seepage field of underground power station of Baise hydroproject is calculated in detail and some evaluations and suggestions are put forword on the design mesure of seepage control of the part of the power station.
