Problems solved by technology

[0004] In view of engineering practice, the influencing factors of structural carbonation need to be considered more comprehensively. A structural carbonation life model for engineering reality should be established to guide engineering design, construction and maintenance. However, the input factors required by traditional structural carbonation life models are often relatively one-sided. , so that there are limitations in carbonation life prediction using the corresponding structural carbonation life model

Abstract

The invention discloses an underground reinforced concrete structure carbonization life intelligent modeling method based on big data. The method comprises the steps: selecting main factors influencing the carbonization life of an underground reinforced concrete structure according to the carbonization mechanism of the reinforced concrete structure and the consideration of an actual engineering situation; according to different factors influencing the carbonization life of the underground reinforced concrete structure and a theoretical model, establishing three-factor and seven-factor sample data; compiling an intelligent genetic algorithm program based on MATLAB, obtaining a corresponding carbonization life model through training according to different sample data, comparing and verifyingcalculation values of a three-factor carbonization life model and a seven-factor carbonization life model with an actual value of the data, and proving the robustness of the intelligent genetic algorithm program for establishing the models and the reasonability of the modeling method ; and finally, collecting actual engineering data in a carbonization environment, establishing a structural carbonization life model considering multiple factors of engineering by utilizing an intelligent algorithm (GP) program, and verifying the engineering practicability of the model by utilizing the actual engineering data.

Description

technical field [0001] The invention relates to the field of tunnel failure life prediction, in particular to an intelligent modeling method for carbonation life of underground reinforced concrete structures based on big data. Background technique [0002] In underground structures, carbonation of reinforced concrete is one of the main reasons for reducing the durable life of structures. The inner side of the reinforced concrete lining of the underground structure is exposed to a semi-enclosed air environment, the air circulation is not smooth, and the relative temperature difference between the inside and the outside is small. 2 The concentration is more than 5 times that of the general atmospheric environment. CO inside the structure 2 The gas migrates and diffuses into the lining, dissolves in the pore water of the lining concrete, and then interacts with the alkaline hydration products (such as Ca(OH) 2 ) reacts to produce carbonate or other substances, which destroys...
