PREDICTION METHOD OF SUBSOIL FROST HEAVE AND SETTLEMENT
To provide a prediction method of subsoil frost heave and settlement capable of more simply and accurately predicting subsoil frost heave and settlement when freezing subsoil by a frozen subsoil method.SOLUTION: A prediction method of subsoil frost heave and settlement comprises: a first step of modeling in advance a frozen subsoil so that each construction section of the frozen subsoil has equivalent area in a block shape and calculating an average frost heave and settlement ratio of each construction section; a second step of classifying each frozen subsoil section into a non-frozen subsoil region, a frozen subsoil region, and a thawed subsoil region according to a construction time; and a third step of selecting the average frost heave and settlement ratio calculated in the first step according to the classified range and obtaining displacement of the subsoil by a three-dimensional frost heave displacement calculation method.SELECTED DRAWING: Figure 1
【課題】より簡便且つ精度よく、凍土工法により地盤を凍結する際の地盤の凍上・沈下量を予測することを可能にする地盤の凍上・沈下量予測方法を提供する。【解決手段】予め凍土の施工区分毎にブロック形状で面積等価となるように凍土をモデル化するとともに、施工区分毎の平均凍上・沈下率を算出する第一の工程と、施工時期に応じて各凍土区分を「未凍土範囲」、「凍土範囲」、「解凍土範囲」に分類する第二の工程と、分類範囲に応じ、第一の工程で算出した平均凍上・沈下率を選択し、地盤の変位を三次元凍上変位計算法により求める第三の工程とを備える。【選択図】図１
