EMBANKMENT WIDENING METHOD AND EMBANKMENT
To widen an embankment without requiring the construction of steps on an existing embankment.SOLUTION: An embankment widening method is a method for widening an embankment by constructing a widening embankment 3 on an existing embankment 1. This method includes a step of providing a connection layer 2 for the sloping surface of the existing embankment 1, and a step of constructing the widening embankment 3 by piling earth on the connection layer 2. The connection layer 2 has water permeability, and its internal friction angle is larger than that of the existing embankment 1. The N value of the connection layer 2 is larger than those of the existing embankment 1 and the widening embankment 3. The connection layer 2 has a plurality of steps 21 on a surface on the widening embankment 3 side.SELECTED DRAWING: Figure 1
【課題】盛土を拡幅する際に、既設盛土への段切りの施工を不要とする。【解決手段】盛土拡幅工法は、既設盛土１に腹付盛土３を施工して盛土を拡幅する工法である。この工法は、既設盛土１ののり面に接続層２を設ける工程と、接続層２の上に土を盛って腹付盛土３を施工する工程とを有する。接続層２は、透水性を有し、その内部摩擦角が既設盛土１の内部摩擦角より大きく、Ｎ値が既設盛土１及び腹付盛土３のＮ値より大きく、腹付盛土３側の面に複数の段２１を有する。【選択図】図１
