<p>Provided are an underground box structure for reinforcing a concrete wall and a slab using preflexion of a reinforcing member and a method for reinforcing same. The method, which is provided to reinforce an underground box structure, includes the steps of: arranging a curved reinforcing member on the upper part and the side wall; introducing a preflexion load into the reinforcing member using the wall as a support; installing a spacing material between the wall and the reinforcing member to be fixed; generating a cross-sectional force corresponding to a cross-sectional force by an operation load through both end points of the reinforcing member and an intermediate spacing member; and adding stiffness of the reinforcing member, thereby improving load resistance performance of the underground box structure.</p> |
