(中國兵器工業(yè)第五設計研究院 北京 100053)[提要] 用低標號混凝土樁加固軟弱地基,可以密實土質(zhì),提高剛度,減小變形。該法已用于高精密車床基礎的防微振,并取得成功,成為不用彈簧等隔振材料防微振的新做法。
[關鍵詞] 地面振動 軟弱地基 剛度比 防微振The soft base strengthened by low strength of concrete piles can make the soil dense, raise the stiffness and decrease the deformation. Without vibration-isolator of spring or other, this is a new and successful try for micro-vibration proof of high precise lathe foundation.
Keywords: vibration of ground; soft base; stiffness ratio; micro-vibration proof
