（福州市自來水總公司 350001）[提要] 針對軟土地基上筏式基礎(chǔ)房屋，探討了水平掏土法糾偏的一些理論性問題。詳細(xì)分析了挖寬比叭挖深比導(dǎo)和荷載偏心率￡對基底應(yīng)力的影響及其規(guī)律，提出了掏土糾偏的設(shè)計計算方法，并簡要介紹了一個工程實例，可供掏土糾偏設(shè)計、施工時參考應(yīng)用。
[關(guān)鍵詞] 糾偏 掏土 筏式基礎(chǔ) 軟土地基Some basic problems of rectifying settlement of mat foundation under a building setting on soft clay by drawing-out soils homontally are studied. The influence of width rati0 9,depth ratio￡as well as load eccentricity on base pressure and its regulars are expounded. A design method of rectifying settlement is suggested, and an engineering example is briefly introduced, which may be useful for design and working.
Keywords: rectifying settlement; drawing-out soil; raft foundation; soft foundation
