GROUND VIBRATION REDUCING DEVICE AND GROUND VIBRATION REDUCING METHOD
PROBLEM TO BE SOLVED: To provide a ground vibration reducing device and a ground vibration reducing method that do not require excavation to a great depth, earth retaining and closing of an opening as in a case of vibration-proof groove formation, do not increase the costs of temporary construction excessively because back-filling and earth retaining wall removal at the time of construction end are not required, do not require excessive costs for construction and removal of a wall body as in a case of vibration-proof wall formation, do not alter a ground structure or affect an inclination in surrounding grounds, and can reduce vibration from construction work for certain.SOLUTION: A ground vibration reducing device includes a frame 2 buried under a ground 1 and installed on a supporting ground 11, a vibration-proof body 3 installed on the frame, and a mass body 4 mounted on the vibration-proof body, the mass body being allowed to change its weight. The ground vibration reducing device adjusts the weight of the mass body and an elastic coefficient of the vibration-proof body, for vibrating at a vibration number that resonates with the vibration number of an object to be controlled.SELECTED DRAWING: Figure 1
【課題】防振溝形成の場合の様に、大深度の掘削や土留および開口部閉塞を必要とせず、また工事終了時の埋戻しや土留撤去を必要としないので工事仮設のコストが多大とならず、また、防振壁の形成のように、壁体の施工や撤去に多大のコストを必要とせず、地盤構造の改変をきたし、周辺地盤に傾斜等の影響を与えることがなく、確実に工事振動を低減できる地盤振動低減装置および地盤振動低減工法を提供する。【解決手段】地盤１中に埋設され支持地盤１１上に設けられる架台２と、架台上に設置される防振体３と、防振体上に載置され重量が変更可能とされた質量体４とを有して地盤振動低減装置を構成し、地盤振動低減装置は、質量体の重量と防振体の弾性係数とを調整して制御対象の振動数と共振する振動数で振動する振動体とした。【選択図】図１
