The invention discloses a mass concrete temperature control method based on intelligent learning. The mass concrete temperature control method comprises the steps of: step S1, acquiring raw data of mass concrete; step S2, pre-processing the raw data to form a data warehouse; step S3, reading relevant data from the data warehouse according to a task; step S4, utilizing a plurality of algorithms toperform data mining analysis, so that the system can continuously carry out intelligent learning based on input data; step S5, performing analysis and utilization of data mining results, comprising intelligent optimization of a target temperature control curve, intelligent prediction of an actual temperature control curve, intelligent control of f water through heat exchanging measures and intelligent feedback of heat preservation and heat dissipation measures; step S6, and starting a new monitoring circulation as a temperature state of the mass concrete develops toward the optimal direction.By adopting the mass concrete temperature control method, the closed-loop intelligent control of temperature of the concrete can be realized, the generation of the target temperature control curve, prediction of the actual temperature control curve and linkage control of ''internal water supply and external heat preservation'' are realized simultaneously, the temperature control quality and efficiency can be significantly improved, and the cracking risk of the mass concrete can be reduced.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of large-volume concrete temperature control and anti-cracking, and in particular relates to a method for temperature control of large-volume concrete based on intelligent learning. [0003] 【Background technique】 [0004] Over the past 60 years, the world's dam industry has carried out extensive investigations and studies on dam safety, and has also achieved rich results. But until now there is still a situation of "no dam, no crack". The temperature control and crack prevention of dams is a difficult point in contemporary design. The bottleneck point is related to the refinement of hydraulic structure design, and is related to the long-term operation safety and security of high arch dams. Stablize. To change this "no dam, no crack" situation, it is the key to intelligently control the temperature of the concrete through water heat exchange (cooling) during the pouring stage, so that no damage cracks will ap...

Problems solved by technology

[0007] It can be seen that the above existing technologies are still mainly based on the traditional finite element simulation method to carry out concrete temperature control. Due to the long period of finite element calculation and the simplification of the model during calculation, a large amount of data related to the monitoring object It is not fully utilized, and the accuracy of monitoring is greatly affected. The real-time perception, real analysis and dynamic control of the full cycle of concrete temperature cannot be realized solely based on the finite element simulation method
