SOFT GROUND IMPROVEMENT AND BANKING REINFORCEMENT METHOD FOR WIDENING OF EMBANKMENT
PROBLEM TO BE SOLVED: To provide a soft ground improvement and banking reinforcement method for widening of embankment, which can prevent a decrease in stability of the whole banking and subsidence of bearing ground subsidence after service is started after construction, in the case of the construction for the widening of embankment.SOLUTION: In a soft ground improvement and banking reinforcement method for widening of embankment, a natural ground reinforcing material 17 for reinforcing a toe of slope of existing banking is constructed by a natural ground reinforcing soil construction method such as a nailing construction method so that the existing banking 13 and the widening 15 of embankment can be integrated together. A structure 12 for ground improvement under the widening 15 of embankment is constructed to improve stability of the whole banking and prevent the deformation and subsidence of the existing banking and the widening of embankment from being caused by consolidation settlement of bearing ground.
【課題】 腹付盛土を施工する場合、施工後に供用を開始した後に盛土全体の安定性の低下や支持地盤の沈下を防止することができる、腹付盛土のための軟弱地盤改良・盛土補強工法を提供する。【解決手段】 腹付盛土のための軟弱地盤改良・盛土補強工法において、既設盛土のり尻を補強する地山補強材１７をネイリング工法等の地山補強土工法を用いて施工することによって前記既設盛土１３と腹付盛土１５とを一体化させるとともに、前記腹付盛土１５下の地盤改良のための構造体１２を施工することによって盛土全体の安定性を向上させ、支持地盤の圧密沈下に伴う既設盛土および腹付盛土の変形・沈下を防ぐようにした。【選択図】 図１
