本文介绍了反演坝体混凝土物理参数的两种方法(常规反演分析法和用确定性模型反演法).在应用常规反演法时,必须重视坝体变形及高水位的影响.在水压和温度分量相互独立的情况下,用水压分量反演的弹模较为准确.而用位移确定性模型反演法可一次推求得坝体混凝土弹模和线膨胀系数,避免了水压分量与温度分量相互替代对反演精度的影响.并用佛子岭连拱坝13号垛的观测资料进行了分析,验证了上述的理论和方法.
In this paper, two methods to retrieve the concrete physical parameters of the dam body (conventional inversion method and deterministic model inversion method) are introduced.When the conventional inversion method is applied, the influence of dam deformation and high water level must be emphasized. When the hydraulic and temperature components are independent of each other, the elastic modulus retrieved from the water pressure component is more accurate, while using the displacement deterministic model inversion method, the elastic modulus and linear expansion coefficient of the concrete can be inferred once, Component and temperature components of the inversion accuracy of the inversion.And the use of Fuziling arch dam No. 13 stacks of observations were analyzed to verify the above theory and methods.
