Rock breaking mechanism and coupling effect rule between cutter tool and surrounding rock were researched, in order to resolve the shield construction problem of shield cutter tool breaking rock. The optimal broken rock cutter spacing of some common rocks was put forward, and the broken rock mechanism of multi-tool is perfected. Considering the impact of various factors,this paper obtains a new calculation method of compound shield total thrust force and cutter-head torque with mathematical and mechanical methods. The research results can be used for design of thrust force and torque, tool selection and arrange.
