The laboratory test of reinforced concrete pile foundation cutting by shield cutterhead is carried out, and 6 sets of driving test schemes for direct cutting with full cutterhead disc cutters and that with full cutterhead tearing cutters are designed respectively for shield crossing pile foundations. Through the statistical analysis of the pile foundation cutting effect, the failure form of steel, the vibration characteristics of cutterhead and the damage form of cutters, the cutting principles of the two kinds of cutters are revealed, and the advantages and disadvantages of the cutters are evaluated. Based on the variation characteristics of thrust and torque of cutterhead under different driving parameters, the combination scheme of disc cutters and tearing cutters and reasonable driving parameters are proposed. The applicable results show that the reinforced bar can be completely cut to short pieces to pass through screw conveyor, improve construction efficiency and reduce risk of chamber opening.
