Abstract: In order to prevent the metro tunnel construction safety accidents, a clustering analysis was made for the cluster was established data on both 57 accidents and 186 near misses using the by ISODATA clustering algorithm. Safety risk rules and management countermeasures were explored for metro shield construction by means of making a comparison between quantification results of the relative risk possibility of the clusters. The results show that the complicated geologic conditions, improper soil reinforcement and drainage at the launching-arrival stage are the most dangerous risk factors in metro shield construction, and that to improve the safety management performance of metro shield construction, the safety production technology of construction should be used at the launching-arrival stage.

Key words: shield construction, safety risk, near miss, safety production technology of construction, iterative self-organizing data analysis algorithm(ISODATA)
