Abstract

The invention discloses a large-volume concrete temperature control method based on intelligent learning. The method includes: step S1: collecting raw data of mass concrete; step S2: preprocessing the raw data to form a data warehouse; step S3: reading relevant data from the data warehouse according to tasks; step S4: using various The algorithm conducts data mining analysis, so that the system can continuously carry out intelligent learning based on the input data; Step S5: Analysis and utilization of data mining results, including intelligent optimization of the target temperature control curve, intelligent prediction of the actual temperature control curve, and water heat exchange measures Intelligent control and intelligent feedback of thermal insulation and heat dissipation measures; Step S6: The temperature state of the mass concrete develops towards the optimal direction, and a new monitoring cycle is started. By adopting this method, the closed-loop intelligent control of the concrete temperature can be realized, and at the same time, the generation of the target temperature control curve, the prediction of the actual temperature control curve, and the joint control of "internal water and external heat preservation" can be realized, which can significantly improve the quality and efficiency of temperature control and reduce large Risk of volumetric concrete cracking.

Description

【Technical field】 [0001] 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. 【Background technique】 [0002] 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 appear from the b...

Problems solved by technology

[0005] 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
