摘要
利用邓肯非线性弹性模型的有限元分析方法,计算地基的应力场与变形场,并以塘沽某高层建筑为例,分析计算天津软土地区非均布荷载作用下不均匀地基建筑物的沉降和差异沉降,利用其计算结果,确定桩端持力层,同时与其它方法计算结果与实测进行比较表明,该方法计算准确,对天津软土地区是十分适宜的。
Using FEM of Duncan non-linear elastic model, the foundation stress and deformation fields are calculated. An high-storied building in Tanggu taken as an example, the settlements and differential settlements are analysed for the building on the soft soil foundation. The tip bearing layer is determined through the calculation results. The comparison of the measured data with those obtained from other methods display the precision of our method, and its suitableness to the areas of Tianjing.
