Early warning method and system of shield construction failure based on association rules

Abstract

The present invention discloses an early warning method and system of shield construction failure based on association rules. The method comprises the following steps: S1 acquiring shield design data,a geological type, construction data and warning data in historical projects; S2 pre-processing the construction data and encoding the geological type and a warning type corresponding to the pre-processed construction data; S3 respectively acquiring an association rule of the warning type for the construction data of different shield models under different geological types according to the encoded geological type and the warning type; and S4 querying the association rule of the warning type according to the warning type in the current shield construction, and performing an early warning on afailure to be generated, to complete the early warning of the shield construction failure. The method can effectively help construction personnel to correct improper construction operation in time ormake corresponding emergency measures in advance according to the early warning of the failure to avoid the occurrence of the failure or shorten failure processing time and effectively improve the efficiency of the shield construction.

Description

technical field [0001] The invention relates to the field of shield construction fault early warning, in particular to a shield construction fault early warning method and system based on association rules. Background technique [0002] The shield construction method is a fully mechanized construction method with a high degree of automation and informatization in the construction of the underground excavation method. It pushes the shield machine in the stratum, and supports the surrounding rocks through the shield shell and segments to prevent the collapse into the tunnel. It is a mechanized construction method in which the tunnel structure is formed by assembling prefabricated concrete segments by means of jacks at the back of the tunnel. [0003] The shield construction method has the advantages of high degree of mechanization, fast construction speed, little adverse impact on the environment, safety and intelligence. Especially in the case of complex and changeable cons...

AI Technical Summary

Problems solved by technology

[0005] Due to the complexity of the shield construction process, there are hundreds of types of faults in the process. In order to ensure the smooth progress of the construction process and the construction quality, the construction personnel need to deal with the faults that occur, and the fault processing process will consume a certain amount of time. and material resources; at the same time, there are many types of failures, and there are correlations between some failures. For example, one failure is often accompanied by another failure. If one failure is not handled in time, another failure will follow. Troubleshooting time increases accordingly, delaying project duration
