The excavation surface model of the composition geologic strata for the shield machine was established, in which the soft soil and hard rocks are taken into account simultaneously. In terms of the cutting mechanism of the individual disc cutter and drag scraper, the total bending moment model on the cutterheads of shield machines was proposed. The bending moment behavior was discussed when the shield machine excavates in the composition geologic strata.
