GROUND VIBRATION PREDICTION METHOD
To provide a ground vibration prediction method that predicts ground vibration in the vicinity of a proposed new viaduct when a train is driven over the new viaduct, which obtains a prediction with higher accuracy by using measured data of ground vibrations in similar ground.SOLUTION: A ground vibration prediction method includes: an actual vehicle measurement step of measuring as first vibration data a vibration input from an existing viaduct to a reference ground 10 via a bridge pier 110 when a train 30 passes at a reference measurement position around the bridge pier; and a vibration prediction step of predicting a ground vibration of an object ground when the first vibration data is input, which corresponds to the position of the bridge pier of the new viaduct in the object ground. Here, the existing viaduct and the new viaduct are provided with footings 116 at the lower ends of the respective bridge piers, and a reference measurement position SP is provided outside a projection area where the footings are projected onto the ground surface.SELECTED DRAWING: Figure 2
【課題】新設高架橋の建設予定地で、該新設高架橋に列車を走行させたときに生じる周辺での地盤振動の予測方法において、類似する地盤での地盤振動の測定データを用いて、より高い精度で予測を得ようとする地盤振動予測方法を提供する。【解決手段】列車３０通過時に既存高架橋から橋脚１１０を介して参照地盤１０へ入力された振動を橋脚の周囲の参照測定位置において第１振動データとして測定する実車測定工程と、対象地盤における新設高架橋の橋脚位置に対応させ、第１振動データを入力したときの対象地盤の地盤振動を予測する振動予測工程と、を含む。ここで、既存高架橋及び新設高架橋はそれぞれの橋脚の下端にフーチング１１６を備え、参照測定位置ＳＰがフーチングを地表面に投影した投影領域よりも外側に設けられていることを特徴とする。【選択図】図２
