【摘要】 对位于邯郸市中心的招贤大厦地基沉降与上部结构共同作用分析研究显示,用有限元方法计算地基沉降能够取得良好的结果。与分层总和法比较,有限元方法更适合计算机使用,能得到复杂条件时的地基沉降计算值及地基土反力分布。分析研究还显示,由于考虑了地基土、基础与上部结构共同作用,在基础筏板的全部弯矩中,整体弯矩占主要部分。整体变形类似锅底状,以底部受拉为主要受力状态,同时与基础相接的框架柱根部有很大的弯矩,设计时要充分注意。更多还原

【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.更多还原
