Fault Diagnosis of Cutterhead Failure of Earth Pressure Shield Based on Bayesian Network
摘要
Abstract
As shield disk cutter is a key component of shield machine, studying the risk management of subway construction and shield cutter head failure has great engineering application value. Bayesian network has advantages in event polymorphism, fault logic relation uncertainty and information uncertainty representation and reasoning in complex system fault diagnosis. Based on the experience and research of engineering practice, this paper uses Bayesian network to analyze the failure form and risk mechanism of soil pressure balance shield. Through the expert survey, the probability level of the risk factors of the earth pressure shield based on the polymorphic Bayesian network is constructed. Taking the failure risk of the cutterhead in the construction of the shield tunnel in a metro, the probability level of the failure risk of the cutterhead is analyzed. The key risk factors are judged by the maximum probability path, and the corresponding control measures of the risk factors of the cutterhead failure are put forward. The engineering practice proves the correctness of the research conclusion.关键词
