［摘要］目前糾傾技術(shù)主要依靠過去經(jīng)驗(yàn)來指導(dǎo)工程實(shí)踐，以往的糾傾對象多為多層和低層建筑，高層建筑糾傾尚未形成系統(tǒng)的理論和設(shè)計(jì)施工體系。采用ABAQUS軟件模擬某高層基礎(chǔ)少傾側(cè)開挖卸荷溝糾傾技術(shù)實(shí)施情況，得出卸荷溝最優(yōu)深度為20～25m，與建筑最優(yōu)距離為1m。建議卸荷溝開挖厚度為0-2m，與建筑邊緣距離為1m，開挖寬度為20m，開挖深度為15m。

Abstract:At present, the rectification technology mainly relies on the past experience to guide the engineering practice. In the past, the object of rectification is mostly multi-storey and low-rise buildings, and there is no systematic theory and design and construction system for high-rise buildings. ABAQUS finite element software was used to simulate the implementation of excavation unloading ditch method for rectification on less inclined side of high-rise building foundation to find the optimal depth of the unloading ditch is 20～25m and the optimum distance from building is 1m. It is suggested that the excavation thickness is 0-2m, the excavation distance is 1m, the excavation width is 20m and the excavation depth is 15m.
Keywords:high-rise building; rectification research; finite element simulation; unloading ditch method
