摘要
针对碾压混凝土坝本体及层面影响带计算参数对变形影响的问题,定义了敏感度函数,探讨了变形计算参数的敏感性分析方法;并运用敏感性分析原理对某碾压混凝土坝变形主要计算参数进行敏感性分析,分析结果表明:本体弹模对变形最敏感,层面弹模次之,然后是本体泊松比,层面泊松比最不敏感.分析结果对碾压混凝土坝的变形分析具有一定的参考价值.
This paper aims at the problem of the noumenon and interface calculation parameters in roller compacted concrete（RCC） dam deformation, defines the sensitive function, and studies the sensitivity analysis method of dam deformation calculation parameters and uses the theory of sensitivity analysis to perform the sensitivity analysis of the main calculation parameters in a certain RCC dam deformation. The result shows that sensitivity to deformation, the ontology elastic modulus is the most sensitive; the level elastic modulus is less sensitive, then is the noumenon Poisson ratio; and the interface Poisson ratio is the least sensitive. The analysis result has reference value for analysis of the RCC dam deformation.
