    EVALUATION METHOD FOR FROZEN GROUND AND EVALUATION APPARATUS FOR FROZEN GROUND

    New search for: YAMAUCHI TAKAHIRO

    To provide technique that can evaluate a frozen ground more accurately than conventional technique.SOLUTION: An evaluation method of a frozen ground for evaluating a frozen ground created by a freezing method comprises: a sampling step of sampling the soil at the site where the freezing method is implemented; a specimen preparation step of creating a specimen by reproducing the freezing method on the sampled soil; and an evaluation step of measuring the state of an ice lens in the created specimen with X-rays and evaluating the effect of freezing by image processing.SELECTED DRAWING: Figure 1

    【課題】従来よりも正確に凍結地盤を評価できる技術を提供する。【解決手段】凍結工法によって造成される凍結地盤を評価する凍結地盤の評価方法であって、凍結工法を実施する現場の土をサンプリングするサンプリング工程と、サンプリングした土に対して、凍結工法を再現して供試体を作成する供試体の作成工程と、作成した供試体におけるアイスレンズの状態をＸ線で計測し、画像処理によって、凍結による影響を評価する評価工程と、を含む。【選択図】図１
