混凝土坝参数的随机反分析方法探讨

Study on Stochastic Back Analysis for Parameters for Concrete Dam

针对混凝土坝施工与运行过程中存在诸多的不确定性因素,基于随机理论和结构计算成果的分析,提出混凝土坝材料参数的随机反分析方法,研制开发了相应的优化计算分析程序。实例表明,随机反分析方法能较好地应用于混凝土坝材料参数的反演和识别中。

Pointing to uncertainties in process of the construction and operation of concrete dam , the method of stochastic back analysis of material parameters is put forward on the basis of stochastic theory and structural analysis. The corresponding optimizational analysis program is developed. This case shows the method can be applied to the back analysis and identification of the material parameters for concrete dam.
