The invention relates to a freeing method of shield cutting tool abrasion and being stuck. Comprehensive consideration is given to the situation of the tunnel face of an opening point, the geologicalconditions, the limit of the ground construction site and the requirements of the time limit for the construction period, surface precipitation, rotary pile retaining soil digging and soil body replacing above and beside a reinforcement notch are conducted, slip casting and reinforcing and other methods are combined, and normal pressure cabin opening detecting and cutting tool changing are conducted. After pressure cabin opening and cutting tool changing and maintaining, tunneling is slowly conducted at low torsion and low rotating speed, and the shield can exit from a cave smoothly.
