Shield attitude real-time prediction system and prediction model building method

Abstract

The invention relates to a shield attitude real-time prediction system and a prediction model building method. The shield attitude real-time prediction system comprises an interactive subsystem havinga data mutual two-way transmission function, a database subsystem and a model base subsystem, wherein the interactive subsystem is used for front end display, and used for operating and transmittingmodel analysis and data query results; the database subsystem is used for storing and managing various data in the shield project construction process, and comprises a source database, a data acquisition module, a decision support database, a data directory module and a query module; and the model base subsystem is used for conducting modeling analysis and providing analysis results, and comprisesa model base, a model directory module, and a training and decision-making platform. According to the shield attitude real-time prediction system and the prediction model building method, the tunneling attitude is predicted in real time through real-time parameters in the shield tunneling process, and the decision-making speed and project quality of the construction site are effectively improved.

Description

technical field [0001] The invention relates to a system and a modeling method for a shield tunneling construction project, in particular to a real-time prediction system for a shield posture and a construction method for a prediction model. Background technique [0002] In the shield construction project site, the difficulty and focus of decision-making business is the management and control of shield tunneling, in which the tunneling attitude of shield tunneling equipment is the key link that affects the construction quality, safety and progress. At present, scholars at home and abroad have conducted research on the shield attitude control decision-making problem in the following aspects: [0003] (1) Pay attention to the daily monitoring of the attitude of the shield on the construction site and the attitude adjustment technology after the offset occurs, and establish the attitude adjustment model and the attitude control model, including the control of the tunneling traj...
