This invention provides a method for calculating segmented discontinuous solar radiation temperature gradients in enclosed stacked aqueducts, relating to the field of aqueduct technology. The method divides the inner cavity of the enclosed stacked aqueduct into a gas-phase coupled heat transfer zone, a gas-liquid phase interface zone, and a fluid heat source anchoring zone based on water level height, constructing a thermo-solid coupled heat transfer model that distinguishes the properties of the media. Through this partitioning, the heat exchange characteristics of different regions can be accurately matched, establishing a segmented discontinuous solar radiation temperature gradient kernel function along the height coordinate. Based on the thermo-solid coupled heat transfer model that distinguishes the properties of the media, the discontinuous solar radiation temperature gradient kernel function is used as a boundary driving source, substituted into the transient nonlinear heat conduction partial differential equation for iterative solution, outputting a discontinuous solar radiation temperature gradient curve containing abrupt step characteristics at the water surface line. This method solves the problem of inaccurate calculation of solar radiation temperature gradients in enclosed stacked aqueducts and is applicable to the calculation of solar radiation temperature gradients in enclosed stacked aqueducts.
