Problems solved by technology

[0002]At present, most pumped storage dams are constructed of roller compacted concrete. Both the reservoir dam and the upper reaches of the lower reservoir dam are subjected to the repeated influence of low water level and high water level, and the repeated influence of water temperature and air temperature makes the surface temperature and stress also change periodically, which is prone to surface cracks

Abstract

The invention provides a pumped storage dam surface temperature and stress analysis method and device and a storage medium, and relates to the technical field of data analysis. The invention providesa pumped storage dam surface temperature and stress analysis method and device and a storage medium. The method includes: according to a pre-constructed concrete structure calculation model and a pre-set calculation scheme, calculating a temperature field by adopting a temperature field calculation formula; calculating a stress field by adopting a stress field calculation formula; obtaining the space-time distribution rules of the temperature and the stress under different conditions; and according to a space-time distribution rule, based on a preset temperature and stress development processcurve of the feature points, analyzing the temperature and stress values of the water level change region under the condition of water level fluctuation and the temperature and stress values of the water level change region under the condition of no water level fluctuation, thereby realizing effective analysis of the temperature and stress of the water level change region.

Description

technical field [0001] The present disclosure relates to the technical field of data analysis, in particular, to a method, device and storage medium for analyzing the surface temperature and stress of a pumped storage dam. Background technique [0002] At present, pumped storage dams are mostly built of roller compacted concrete. The working characteristics of pumped storage dams determine that the water level of the pumped storage dam is a large water level change. Both the upper and lower reservoir dams are subjected to low water levels. The repeated influence of water level and high water level, and the repeated influence of water temperature and air temperature make the surface temperature and stress also change periodically, which is prone to surface cracks. Contents of the invention [0003] Based on the above research, the present disclosure provides a method, device and storage medium for analyzing the surface temperature and stress of a pumped storage dam. [000...
