常规的研究发现，高拱坝高坝大库所产生的库盘变形影响是必然存在的，由于其变形规律的不明确性，有必要对高坝大库的库盘变形规律进行研究。本文仅考虑库盘变形的弹性部分，利用线弹性有限元方法，建立高拱坝大范围直线型河道库盘有限元模型，通过数值分析方法研究直线型河道库盘变形规律，并确定合理的库盘建模范围，在此后实际工程的坝体变形分析中，为全面考虑库盘变形对坝体变形性态的影响奠定了基础，确保能够有效地监控大坝的安全运行。

Regular study discovers that base plate deformation influence produced by high arch dam high-dam reservoir is inevitable.It is necessary to study the base plate deformation law of high-dam reservoir because of the uncertainty of the deformation law.In the paper,only elastic part of base plate deformation is considered,and linear elastic finite element method is utilized for establishing high arch dam wide range linear river channel base plate finite element model.The deformation law of linear river channel base plate is studied through numerical analysis method.Rational base plate modeling scope is determined,thereby laying foundation for comprehensively considering the influence of base plate deformation on dam deformation behavior in dam deformation analysis of practical project in the future,and ensuring effective monitoring of dam safe operation.
