SOIL-RETAINING WALL
To materialize an easy construction of a soil-retaining wall.SOLUTION: An earth-retaining wall design method of this invention is for an earth-retaining wall 1 in which a designated horizontal direction is its longitudinal direction D1 as expressed in a horizontal section. The earth-retaining wall 1 comprises: a first earth-retaining material 2, which has concavity parts 2a recessing outwards from the inner face and convex parts 2b protruding inwards from the inner face, both alternately continuing along the longitudinal direction D1; a second earth-retaining material 3, which is separated from the first earth-retaining material 2 with a specific distance L in the width direction D2 perpendicular to the longitudinal direction D1, and which has concavity parts 3a recessing outwards from the inner face and convex parts 3b protruding inwards from the inner face, both alternately continuing along the longitudinal direction D1; and an internal ground 4 that is formed by improvement in which an improvement material is radially agitate-and-injected with an agitation-injection nozzle 5 arranged in the separation space between the first earth-retaining material 2 and the second earth-retaining material 3. The design method for the earth-retaining wall 1 comprises a non-improvement-part-setting step S1 to set non-improvement parts 6 that include spots hidden from the agitation-injection of the improvement material, and a modeling-analysis step S2 that models the earth-retaining wall 1 including the non-improvement parts 6 to analyze.SELECTED DRAWING: Figure 1
【課題】土留め壁の容易な施工を実現する。【解決手段】所定水平方向を水平断面での長手方向Ｄ１とする土留め壁１の設計方法であって、土留め壁１は、内面から外側に窪む凹部２ａと内面から内側に突出する凸部２ｂが長手方向Ｄ１に交互に連続する第１土留め材２と、第１土留め材２に対して長手方向Ｄ１と直交する幅方向Ｄ２に所定距離Ｌを離隔し、内面から外側に窪む凹部３ａと内面から内側に突出する凸部３ｂが長手方向Ｄ１に交互に連続する第２土留め材３と、第１土留め材２と第２土留め材３の離隔した離隔空間に配置される撹拌噴射ノズル５によって改良材を放射状に撹拌噴射する改良によって形成される内部地盤４と、を有し、改良材の撹拌噴射の際に陰となる部分を含む不改良部６を設定する不改良部設定ステップＳ１と、不改良部６を含む土留め壁１をモデル化することで解析をするモデル化解析ステップＳ２と、を有する土留め壁１の設計方法。【選択図】図１
