    PROBLEM TO BE SOLVED: To provide a strength management method of a back filling material to allow a management to control strength of a back filling material simply and precisely.SOLUTION: The invention is a strength management method for a back filling material composed of mixing water, soil particles, bentonite, and cement. The method comprises: a setting step to set a constant specified in accordance with a type of bentonite; and a determining step to determine a quantity of water W, a quantity of bentonite B and a quantity of cement C, all of which are mixed to acquire a target strength qusing a strength calculation formula embedded with the constant a. For example, the strength calculation formula is shown as q=2.36(C/(W-a*B))-0.23.SELECTED DRAWING: Figure 1

    【課題】埋戻し材の強度を簡単かつ正確に管理できるようにする埋戻し材の強度管理方法を提供する。【解決手段】水と土粒子とベントナイトとセメントとが混合された埋戻し材の強度管理方法である。この方法では、ベントナイトの種類によって特定される定数aを設定するステップと、その定数aが組み込まれた強度算定式を使用して、目標強度quとするために配合される水量W、ベントナイト量B及びセメント量Cを決定するステップとを備えている。例えば強度算定式は、qu=2.36(C/(W-a×B))-0.23で示される。【選択図】図１
