摘　　要：采用固定网格的结点虚流量法进行构皮滩拱坝坝基三维渗流场分析,建立了拱坝及坝基的整体三维非线性有限元计算模型,研究了坝体、坝基的变形应力分布规律以及屈服区、开裂区影响范围,并进行了坝体、坝基的整体稳定性分析,对构皮滩拱坝的初步设计方案作出了科学、合理的评价。The three dimensional foundation seepage field of the Goupitan arch dam is analyzed by use of the nodal virtual flow rate method of an unvaried mesh. A whole nonlinear finite element model of the dam and its foundation is established. The stress distribution and the influence scope of yielded and cracked areas are studied. The stability of the dam and its foundation is analyzed and the scientific and reasonable evaluation on the preliminary design of Goupitan arch dam is made.
