To provide a ground investigation method that enables a certain degree of estimation of a prior research stage such as document survey for grounds with large liquefied ground and surface ground amplification.SOLUTION: Provided is a ground investigation method to investigate the situation of the ground from the existing data. The method comprises a preparing step of preparing in advance data of ground constants relating to the strength to a predetermined depth of the surveyed ground including the surroundings, data of groundwater level and data of terrain classification, a sorting step (step S1) of determining whether or not the ground constant up to a predetermined depth exceeds the strength threshold, a water level determining step (step S2) of determining whether the groundwater level exceeds the water level threshold value, a liquefaction determining step (step S3) of determining whether or not it corresponds to a specific topography A having a possibility of liquefaction from the data of the topography classification, and an amplification determining step (step S4) of determining whether or not it corresponds to a specific topography B where there is a possibility that surface ground amplification may occur.SELECTED DRAWING: Figure 1
【課題】液状化地盤と表層地盤増幅の大きい地盤についても、資料調査などの事前調査の段階である程度の推定が可能となる地盤調査方法を提供する。【解決手段】地盤の状況を既存のデータから調査する地盤調査方法である。そして、周辺を含む調査対象地盤の所定深度までの強度に関する地盤定数のデータ、地下水位のデータ及び地形分類のデータを予め準備する工程と、所定深度までの地盤定数が強度閾値を超えているか否かを判定する選別工程（ステップＳ１）と、地下水位が水位閾値を超えているか否かを判定する水位判定工程（ステップＳ２）と、地形分類のデータから液状化の可能性が有る特定地形Ａに該当するか否かを判定する液状化判定工程（ステップＳ３）と、表層地盤増幅が起きる可能性が有る特定地形Ｂに該当するか否かを判定する増幅判定工程（ステップＳ４）とを備えている。【選択図】図１
