Abstract

The invention belongs to the technical field of general control or adjustment systems, and specifically relates to a deviation correction control method and device for shield tunneling posture. The method includes: constructing a deviation correction principle model of a shield machine; the deviation correction principle model includes a deviation correction trajectory curve; determining the deviation correction principle The minimum correction radius of the model; the minimum correction radius of the correction principle model is the curvature radius of the correction trajectory curve; the artificial ant colony algorithm is used to process the preset shield machine parameters to obtain the optimal feature subset; according to the minimum correction radius and the most The optimal feature subset is used to construct the deviation correction mathematical model of the shield machine; based on the deviation correction mathematical model, the control parameters are obtained by optimizing the optimal feature subset through the artificial bee colony algorithm; and according to the control parameters, the tunneling posture of the shield machine is controlled for deviation correction. By introducing the ant colony algorithm, the optimal feature subset can be screened out, and the optimal feature subset can be used as the initial population of the artificial bee colony algorithm, which can improve the solution quality, improve the accuracy of deviation correction, and achieve better deviation correction effect.

Description

technical field [0001] The invention belongs to the technical field of general control or adjustment systems, and in particular relates to a deflection correction control method and device for shield tunneling posture. Background technique [0002] With the development of urbanization and the gradual increase of urban population, the construction of subway tunnels has become an important measure to relieve traffic pressure and improve the urban environment. Open cut method and shield method are the main methods of subway tunnel construction. Using the open-cut method, the initial masonry and other work are completed in the open air. Factors such as terrain, landform, construction environment, and weather have a great influence on the construction, which limits the application range of the open-cut method. The shield tunneling method belongs to the underground excavation method. During the implementation, the shield tunneling machine completes the excavation, initial laying,...

Problems solved by technology

However, because the artificial bee colony algorithm is easy to fall into the problem of local optimum, which leads to low optimization accuracy and slow convergence speed, the accuracy of the solution results of the deviation correction model is reduced, and the practicability is not strong.
