Zusammenfassung:The present invention relates to a slope construction method for economically preventing subsidence and horizontal displacement of an adjoining structure using material characteristics and a structure constructed thereby, which can minimize subsidence and horizontal displacement of an adjoining structure when a structure is excavated close to the adjoining structure. The slope construction method includes the steps of: (a) constructing auxiliary vertical stiffeners to be spaced from each other by injecting a grouting material into a hole, and then constructing main vertical stiffeners to be overlapped between the spaced auxiliary vertical stiffeners so that the vertical stiffeners are constructed adjacent to a structure without subsidence and horizontal displacement; and (b) forming holes in the rear surfaces of the auxiliary vertical stiffeners and stirring the grouting material in the disturbed ground in order to construct a slope stiffener which is a downwardly inclined large caliber anchor body. 구조물 근접 굴착 시 인접구조물의 침하 및 수평변위 발생을 최소화할 수 있도록 하면서 재료적 특성을 이용하여 경제적인 인접구조물 침하 및 수평변위 방지가 가능한 법면시공방법 및 이를 이용하여 시공된 구조물에 관한 것으로서, 상기 시공방법은 (a) 천공홀에 그라우팅재를 주입하여 시공되는 보조연직보강재를 서로 이격 시공한 후, 상기 서로 이격된 보조연직보강재 사이사이에 주연직보강재를 겹치도록 시공하여, 연직보강재를 인접구조물 침하 및 수평변위가 발생하지 않도록 구조물에 근접시켜 시공하는 단계; 및 (b) 상기 보조연직보강재 배면으로 천공홀을 형성시키면서 교란된 지반에 그라우트재를 교반시켜 하방 경사진 대구경앵커체인 경사보강재를 시공하는 단계;를 포함한다.
