A data mining method for shield tunneling parameters of TBM

Abstract

A data mining method for shield TBM tunneling parameters mainly includes two parts: a 16-dimensional combined modeling method for distribution dynamic segmentation statistical analysis and a dynamic core empirical region analysis method for tunneling parameters. While receiving a large number of shield tunneling parameters of TBM on construction lines, accumulated frequency histogram data are periodically aggregated according to the prescribed rolling time window, the histogram core region is calculated according to a certain range, and the core region is judged by a fast reciprocating traversal algorithm, so that the optimal range of tunneling parameters is obtained through the accumulation of large data.

Description

technical field [0001] The invention relates to the field of tunnel shield excavation engineering, in particular to a data mining method for shield TBM excavation parameters. Background technique [0002] At present, China's cableway shield construction is still in the period of rapid development and construction experience in the youth stage, and the digital and intelligent methods for on-site construction are still relatively lacking. Tunnel shield tunneling construction mainly relies on the operation console installed on the equipment by the shield machine manufacturer And the attached built-in computer and instrument panel give the operator of the shield machine the feedback of the current excavation information. The main purpose is to help the operator control the behavior of the shield machine on site. The present invention hopes to solve the data mining of excavation parameters through a shield TBM The method, firstly, reflects the historical construction technical ...

[0002] At present, China's cableway shield construction is still in the period of rapid development and construction experience in the youth stage, and the digital and intelligent methods for on-site construction are still relatively lacking. Tunnel shield tunneling construction mainly relies on the operation console installed on the equipment by the shield machine manufacturer And the attached built-in computer and instrument panel give the operator of the shield machine the feedback of the current excavation information. The main purpose is to help the operator control the behavior of the shield machine on site. The present invention hopes to solve the data mining of excavation parameters through a shield TBM The method, firstly, reflects the historical construction technical parameters of similar shield equipment in each project under similar geological conditions, and reflects the position and level of the current operation process relative to the historical construction; secondly, for operators with limited experience on the job There is no auxiliary information to help judge the current operation process and the construction effect, construction speed, and construction gap of other operators in the historical project construction. Blindly carry out according to personal experience and construction arrangements, which is prone to unreasonable rush or delay. When explaining the problem upwards The excavation data basis cannot be provided; finally, the on-site responsible personnel lack data basis when formulating the construction plan and evaluating the construction effect, and the rear construction management dispatcher cannot compare and evaluate each construction state, so there is an urgent need for a shield tunneling machine based on historical construction effects The data mining method of TBM tunneling parameters can intuitively reflect and compare the data mining method of the tunneling status in the specific construction process
