[摘要]對(duì)位于邯鄲市中心的招賢大廈地基沉降與上部結(jié)構(gòu)共同作用分析研究顯示,用有限元方法計(jì)算地基沉降能夠取得良好的結(jié)果。與分層總和法比較,有限元方法更適合計(jì)算機(jī)使用,能得到復(fù)雜條件時(shí)的地基沉降計(jì)算值及地基土反力分布。分析研究還顯示,由于考慮了地基土、基礎(chǔ)與上部結(jié)構(gòu)共同作用,在基礎(chǔ)筏板的全部彎矩中,整體彎矩占主要部分。整體變形類似鍋底狀,以底部受拉為主要受力狀態(tài),同時(shí)與基礎(chǔ)相接的框架柱根部有很大的彎矩,設(shè)計(jì)時(shí)要充分注意。

Abstract:The analysis on Zhaoxian building indicates that it can get the better results of the foundation settlement and cooperative action by the finite-element method. The finite-element method is suitable for computer to use, and it can get the results of the vertical sectional inner forces of the foundation soil and upper structure in complex case. The results also show that integral moment is the main part of the foundation plate moments, the total deformation is like the pot bottom, and there is great moment at the root of frame column connecting with the foundation, which should be paid attention to in design.
Keywords:building; finite element method; settlement; layerwise method; cooperative action
