Mass concrete construction temperature field control method based on digital twinborn technology
The invention relates to a mass concrete construction temperature field control method based on a digital twinning technology, which comprises the following steps: inverting concrete heat conductivity coefficient, specific heat capacity, hydration degree and other key parameters through limited monitoring data of fixed measuring points in mass concrete, reconstructing a three-dimensional temperature field, and predicting a change rule of the temperature field on the basis of the three-dimensional temperature field. And a cooling measure scheme is adjusted in time, so that the problem that the reconstruction result of the concrete temperature field is distorted due to unreasonable values of key parameters of the heat conductivity coefficient, the specific heat capacity and the hydration degree in the prior art is solved. According to the method, the data twinning technology is applied to mass concrete construction temperature field control, three-dimensional visualization can be carried out on the temperature field through the digital twinning technology on the basis of monitoring data of a small number of measuring points, the development law of the temperature field is predicted, and on the basis, a cooling measure scheme can be adjusted in time, and construction is guided.
