[關(guān)鍵詞] 糾偏 加固 工程 不均勻沉降 無砂混凝土 壓漿 水泥漿Based on analysis of incline caused by ground unequal settlement of a apartment building, the technique of composite pile ground of un-sand concrete grouted with cement paste is used to consolidate the ground and the building.The design scheme of rectifying deviation is presented according to calculation. The construction schemes of drawing out soil and grouting are adopted to accomplish rectifying deviation of the building and achieve expected purpose. The design and construction schemes are introduced as a reference for the same kind of engineering.
Keywords: rectifying deviation; consolidation; engineering; un-sand concrete; unequal settlement
