DESIGN METHOD OF GROUND IMPROVEMENT WALL
PROBLEM TO BE SOLVED: To provide a design method of a ground improvement wall capable of designing the ground improvement wall which can limit a surplus improvement area as much as possible in regard to the design method of the ground improvement wall configured by overlapping a plurality of ground improvement piles to each other.SOLUTION: Provided is a design method of a ground improvement wall to design a ground improvement wall W configured by overlapping a plurality of ground improvement piles P with a circular cross section of a diameter D(m) to each other, in which an inter-pile distance L(m) is regarded as a distance between pile centers of two adjacent ground improvement piles P. An optimum diameter of the ground improvement piles P is designed according to an optimum diameter Dopt(m)={1+(2/π)}×te of the diameter D(m) after determining a designed wall thickness te(m). Furthermore, an optimum inter-pile distance of the ground improvement piles P is designed according to an optimum inter-pile distance Lopt(m)=(2/π)×te of the inter-pile distance L(m).SELECTED DRAWING: Figure 3
【課題】複数の地盤改良杭が相互にラップしてなる地盤改良壁の設計方法に関し、余剰改良域を可及的に抑制することのできる地盤改良壁を設計することのできる地盤改良壁の設計方法を提供する。【解決手段】直径D(m)の断面円形で複数の地盤改良杭Ｐが相互にラップしてなる地盤改良壁Ｗにおいて、隣接する二つの地盤改良杭Ｐの杭中心間の距離を杭間距離L(m)とする地盤改良壁の設計方法であって、設計壁厚te(m)を設定した後、直径D(m)の最適直径Dopt(m)＝｛1＋(2/π)2｝1/2×teで地盤改良杭Ｐの最適直径を設計する。また、さらに、杭間距離L(m)の最適杭間距離Lopt(m)＝(2/π)×teで地盤改良杭Ｐの最適杭間距離を設計する。【選択図】図３
