본 발명은 벽부의 균열 성장을 억제하는 방법에 관한 것이다. 본 발명의 일 실시예에 따르면, 벽부의 균열 성장을 억제하는 방법은 균열에 작업유체를 주입하는 주입단계; 상기 균열의 입구에서 상기 균열의 내측을 향하는 방향으로 상기 작업유체를 가진시키는 가진단계; 및 상기 균열 내의 작업유체에 기공을 발생시킴으로써 상기 균열의 내측 단부에 압축 잔류 응력을 발생시키기 위한 변형단계를 포함한다.

    There is provided a crack repairing method for suppressing a crack growth in a wall portion. The crack repairing method includes an injection step in which working fluid is injected into a crack formed into a surface of the wall portion of a target object and a vibration step in which vibration is applied to the working fluid in a direction from an crack initiation portion of the crack on the surface to an inner end portion of the crack. The crack repairing method further includes a deformation step in which a cavity is generated in the working fluid by the applied vibration and compressive residual stress is generated at the inner end portion of the crack.
