Abstract: The integrity and reliability of the in-situ data are the necessary prerequisites and key factors to promote the development of various industries in the era of industrial big data. As a key equipment of tunnel engineering, tunnel boring machine (TBM) has the characteristics of complex system structure and high relationship between the attributes, and it is a national tool for urban underground construction in national strategies such as “One Belt and One Road”. However, in the process of TBM operation, missing values frequently occurs in the acquisition of measured data of TBM due to various reasons, such as environmental interference, acquisition interruption, equipment failure, which seriously reduces the quality and reliability of data and affects the progress of the project. According to the characteristics of measured data of TBM, a high-precision missing value imputation algorithm based on fuzzy clustering and nonlinear regression is proposed. Firstly, the measured data under different working conditions are divided into several linear subsets by fuzzy clustering method. Then, a linear regression model is established for each subset, and an alternating learning strategy is used to solve the model parameters, which effectively mines the correlation between attributes. Experimental results show that the proposed method performs well both in clustering incomplete data and imputation missing data. The proposed data imputation algorithm can effectively solve the problem of data division and recovery, and provides a reliable foundation for the actual big data mining of shield machine.
