Problems solved by technology

For a long time, the tunneling process of the shield machine has been calibrated and analyzed by manual experts on various parameters in the tunneling process of the shield machine. Although this mode is stable and reliable, it takes a lot of time to teach manual experience, and it cannot be based on the geological section. Small changes can be adjusted in real time, which makes the efficiency of the entire shield machine excavation process still have a large room for improvement

Abstract

The invention discloses a shield tunneling machine tunneling parameter prediction method based on polynomial regression. According to the invention, the big data processing method based on machine learning is applied to shield engineering data processing for the first time; characteristic learning is carried out on shield engineering big data through a machine learning method after cleaning and statistical processing. By means of the data high-level feature extraction capability of a machine learning algorithm, operation parameters and operation efficiency are efficiently modeled, so that instructive suggestions are made for parameter adjustment of a shield in engineering, and the characteristics of artificial intelligence are achieved.

Description

technical field [0001] The invention relates to a method for predicting tunneling parameters of a shield machine based on polynomial regression. Background technique [0002] In recent years, with the rapid development of urban economy, urban construction has gradually expanded to space, and subways have become the focus of urban development. The shield machine is widely used in subway tunnel construction projects due to its advantages of fully enclosed, fast tunneling, and simultaneous lining. In a uniform and single stratum, the construction technology of the shield tunneling method is relatively simple due to its single excavation method and stable excavation parameters; but in the complex stratum, due to the changeable stratum structure, it is necessary to constantly adjust the shield machine The tunneling parameters make it maintain a stable and efficient tunneling speed. How to achieve this goal and increase the speed of advancement while ensuring quality is the core...
