The present invention relates to a method for suppressing growth of cracks. According to one embodiment of the present invention, the method for suppressing growth of cracks on a wall comprises: an injecting step for injecting operation fluid into cracks; an exciting step for exciting the operation fluid toward the inside of the crack from an inlet of the crack; and a deformation step for generating residual compressive stress on an end portion at the inside of the crack by generating a gas hole in the operation fluid within the crack.

    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.
