At present, the understanding of shield construction conditions is mainly based on the data returned by shield machine sensors. However, the variety of shield parameters and the large amount of data make it difficult to directly obtain valuable information from them, especially for super large diameter shields. This paper proposes a method for constructing a Partial Correlation Threshold Network (Partial Correlation Threshold Network, PCTN) based on the tunneling parameters of a super large diameter shield, and introduces the commonly used indicators for quantitative analysis of network topology. Finally, based on the measured data of a super large-diameter cross-river shield tunnel project, a shield parameter network diagram is drawn. By obtaining the macro index of the shield parameter network and the statistical index of the shield parameter itself, the relationship with the excavation surface pressure is analyzed. Correlation of fluctuations. This article provides help for more in-depth exploration of the interaction mechanism between parameters, and the prediction of the stability of the excavation face.
