Abstract

The invention discloses a method for predicting the service life of an underground structure in an acid environment based on data driving, and the method comprises the steps of building a life sample simulation database of multiple influence factors according to different influence factors of the service life of an underground building structure in the acid environment; determining GP parameters needing to be optimized in a genetic programming program and an objective function form, taking given sample data as a drive, and using Python to compile a Harris-Eagle algorithm to optimize the GP parameters; and outputting the GP parameter, the objective function and the objective function value after the HHO algorithm optimization. The invention can be applied to prediction of the service life of the underground structure in the acid environment and has guiding significance on repairing and reinforcing of the underground structure in the acid environment; the established service life prediction model has appropriate training errors and small generalization errors, and the engineering practicability is high.

Description

Technical field

[0001] The present invention relates to underground structural corrosion life prediction, and more particularly to a method of underground structural life prediction based on data-driven acidic environments. Background technique

[0002] In the underground engineering, the acidic environment that can affect the engineering structure is mainly a sulfate environment. The inner side of the underground structure is generally exposed to air without circulating, and the outside is directly in contact with the formation; there is often a sulfate erosion substance in the rock formations in the southwestern region of my country and the inland Salt Lake area. Such erosion environments will have a large destruction of reinforced concrete components of the underground structure, which often lead to a decrease in concrete strength, concrete crisp and forming, which reduces the overall service life of the underground structure.

[0003] Sulfate erosion is a complex physic chemi...
