Method for reconstructing three-dimensional temperature field of concrete structure

The invention provides a method for reconstructing a three-dimensional temperature field of a concrete structure, and the method comprises the steps: building a grid model according to an actual concrete structure, and carrying out the finite element calculation of the three-dimensional temperature field of the concrete structure under any initial and boundary conditions of an actual working condition; establishing a neural network for reconstructing a three-dimensional temperature field of the concrete structure; according to the numerical calculation result of the three-dimensional temperature field of the concrete structure and the neural network for reconstructing the three-dimensional temperature field of the concrete structure, the optimal arrangement distance of the concrete temperature measuring points is determined, and the temperature measuring points are actually arranged; and acquiring spatial position information of each actually arranged temperature measuring point and actual temperature process
