摘　　要：对于大型复杂混凝土结构的设计与施工,必须进行双重非线性分析才能保证工程经济合理及安全可靠。利用样条有限点双重非线性方法对坝体和坝肩岩体抗滑稳定性进行分析,并提出了相应的算法。实际工程分析结果表明,样条有限点双重非线性分析法是进行拱坝和坝肩抗滑稳定性分析的一种有效方法,能够得到经济、安全的加固方案。In design and construction of large complicated concrete structures, the double nonlinear analysis must be carried out for economic and safety reasons. The spline finite point double nonlinear method is suggested to analyze anti-slide stability of the dam body and abutment, then the calculation format is established. Practical example indicates that spline finite point double nonlinear method is an effective way for stability analysis of arch dam and dam abutment, and economical and reliable reinforcing scheme can be obtained by using the method.
