Abstract

PurposeAt present, using the finite element method is difficult to efficiently and accurately construct the temperature field of mass concrete based on temperature measurement points. Thus, there is a need to propose a method for improvement.Design/methodology/approachThis study developed an implicit finite element method that digitally constructs the temperature field of mass concrete based on temperature measurement data. That is, in the proposed method of this paper, the temperature of the measuring point is also one of the boundary conditions, which real-time corrects the calculation error.FindingsIn this method, during the digital construction of the temperature field, the computed temperature approaches the actual measured value at the point of measurement with increasing iteration steps. Using this method and sufficient temperature measurement data, the errors in calculation conditions (such as the boundary conditions, the initial casting temperature and material parameters) can be automatically corrected during the iterative computation process.Originality/valueThis new method can improve calculation accuracy and allows the digitally constructed temperature field to converge to its true value with sufficient measurement data.
基于点温度测量的混凝土结构温度场数字构建隐式求解方法
目的目前,使用有限元法很难根据温度测量点高效、准确地构建大体积混凝土的温度场。设计/方法/途径本研究开发了一种隐式有限元方法,可根据温度测量数据以数字方式构建大体积混凝土的温度场。即在本文提出的方法中,测量点的温度也是边界条件之一,可实时修正计算误差。研究结果在该方法中,在温度场的数字化构建过程中,随着迭代步数的增加,计算出的温度接近测量点的实际测量值。利用这种方法和充足的温度测量数据,可以在迭代计算过程中自动纠正计算条件(如边界条件、初始铸造温度和材料参数)的误差。
