碾压混凝土坝横观各向同性粘弹性参数反演

Retrieval of transversely isotropic viscoelastic parameters for RCC dams

摘要: 针对碾压混凝土的流变特性,选取合适的粘弹性本构模型,结合实测资料,进行碾压混凝土坝粘弹性参数的反演,并编制了相应的反演分析程序.实例表明,该反演方法切实可行.

Abstract: On the basis of the rheological properties of roller compacted concrete,viscoelastic parameters for RCC dams are retrieved by selecting an appropriate viscoelastic constitutive model and considering the measured data,and the corresponding analysis program is developed.Results of the case study show that this method is feasible.
