The rock breaking efficiency of cutter tools of shield machine is low in complex stratum with local high intension bedrocks and boulders. The controlled drilling and blasting method and controlled broken rocks are synthetically analyzed. The influences induced by blasting are systematically classed. The evaluation system of blasting risks of boulder and bedrock intrusion is established. The factor weight and membership function of each risk grade are determined by means of APH method and fuzzy method, so as to estimate the risk acceptable grade. The practice shows that the mentioned methods are reliable and effective.
