Abstract

An aqueduct is an important hydraulic structure for water conveyance, whose safety and durability are directly related to the normal operation of hydraulic projects and the effective allocation of water resources. In this study, based on temperature monitoring data from monitoring points during the segmented casting process of a large-span continuous rigid-frame stacked-box aqueduct. Based on these measurements, the temperature field of the aqueduct’s complex-shaped cross section was reconstructed using Kriging interpolation. An application programming interface (API) for temperature-field visualization was implemented on the Python platform using the PyKrige library, and the spatial distribution characteristics of the reconstructed cross-sectional temperature field were subsequently analyzed. The results indicate that the reconstructed sectional temperature field effectively reveals the spatiotemporal distribution of heat generated by concrete hydration. The temperature distribution between the left and right sides of the aqueduct body is uneven; high-temperature accumulation occurs in the wide-thick regions of the cross section, and large temperature gradients appear at the interfaces between casting segments, for which corresponding thermal-control measures should be adopted to ensure construction quality. This study will provide a design reference for similar casting schemes of large-span continuous rigid-frame aqueducts.
