EARTH RETAINING WALL CORE MATERIAL AND EARTH RETAINING WALL
To provide an earth retaining wall core material capable of increasing the shear strength of the earth retaining wall without increasing the thickness of the earth retaining wall.SOLUTION: An earth retaining wall core material 1 is formed by laminating a plurality of plates made of a fiber-reinforced resin containing reinforcing fibers oriented in one direction. The plurality of plates include at least a first plate 11 and a second plate 12 having different angles in the orientation direction of the reinforcing fibers with respect to the longitudinal direction of the plate in plan view. In plan view, an angle A of the second plate 12 in the orientation direction D2 of the reinforcing fibers with respect to the orientation direction D1 of the reinforcing fibers of the first plate 11 is -45° or more and less than 0°, or more than 0° and 45° or less.SELECTED DRAWING: Figure 1
【課題】土留め壁の厚さを増大させることなく、土留め壁のせん断強度を高めることができる、土留め壁用芯材を提供する。【解決手段】一方向に配向する強化繊維を含む繊維強化樹脂からなる板材を、複数枚積層してなり、前記複数枚の板材は、少なくとも、平面視において前記板材の長手方向を基準とする前記強化繊維の配向方向の角度が互いに異なる第１の板材１１と第２の板材１２を含み、平面視において第１の板材１１の強化繊維の配向方向Ｄ１を基準とする第２の板材１２の強化繊維の配向方向Ｄ２の角度Ａが－４５°以上、０°未満又は０°超、４５°以下である、土留め壁用芯材１。【選択図】図１
