摘　　要：采用通用的有限元程序ANSYS对起关键作用的闸墩颈部和预应力锚块建立模型,并通过改变对预应力效果影响较大的空腔尺寸计算颈部和锚块的应力,通过分析比较最终确定出合理的预应力闸墩空腔锚块的结构型式。A model is established for the analysis on the pier neck with key role on the pier structure and the pre-stressed anchor block of the pier for Pushihe Pumped Storage Hydropower Station based on the finite dement analysis program of ANSYS, and then the pier neck and anchor block are calculated through changing the hollow size that has greater influence on the pre-stressed effect, and finally a reasonable structure of the hollow anchor block for the pressed pier is determined on the basis of the analytical comparison concerned.
