碾压混凝土坝三维粘弹性分析模型研究
hree dimensional viscoelastic model analyzing RCCD
将碾压混凝土施工层面影响带视为横观各向同性体,应用复合材料力学分析理论,深入研究了碾压混凝土坝施工层面影响带的变化规律,提出了具有横观各向同性体性质的渐变规律分析模型,反演分析了反映层面渐变特性的相关参数;据此研究并提出了相应的碾压混凝土三维粘弹性分析模型。实例分析表明,提出的分析模型能较好地反映碾压混凝土施工层面影响带对坝体结构性态的影响。
onstruction interfaces of RCCD are assumed as transversely isotropic bodies.The mechanical analytical theory of compound material is used to study the characters and rules on deformation of construction interfaces.A model is proposed to analyze above problems of transversely isotropic bodies.This paper implements the back-analysis for the parameters reflecting the graded characteristic of construction interfaces.A three dimensional viscoelastic model is presented to analyze the behavior of RCCD.The example shows that the proposed model can describe reasonably the relation between construction interfaces of RCCD and dam behavior.
