摘要
采用有限元方法对观音港电排站进行了三维渗流的数值分析,采用材料与水的特性曲线在分析过程中给出了非饱和区渗透系数和饱和度的确定方法,并给出了材料吸水、干燥过程的确定方法。分析结果充分说明了电排站前池底板翻砂鼓水的原因,为进一步对电排站前池底板的锚固提供了科学的数据分析,同时也说明了该非饱和区渗透系数和饱和度确定方法正确性。
The three dimensional seepage analysis for the power irrigation station of the Guan-yin harbour is used by the finite element method. The determination method of the unsaturated permeability and saturation is given during the analysis by adopting the characteristic material-water curve, and the absorption and exsorption proeess is given. The results show that the damage reason about the front pond of the power irrigation station is sufficiently given, it provides the scientific data analysis to reinforce the master and the correctness of determining the saturation in the unsaturated zone.
