摘    要:基础不均匀沉降将在上部结构内产生附加内力,而且地基变形也是随施工过程逐渐累积的过程.然而,常规计算方法既没有充分考虑上部结构、基础、地基之间的共同作用,也没有反映施工过程对结构内力的影响.针对上述问题,笔者推导了施工过程中地基变形和结构内力的计算公式,提出了考虑土结相互作用并模拟施工过程的实现方法.为研究地基变形和结构内力提供了手段,对采动区土地复垦及抗变形建筑物的设计、施工,防止或减轻地基变形对建筑物的损坏等具有重要现实意义.

关 键 词:土结相互作用  施工过程  地基沉降  结构内力

Abstract:Extra internal force will appear in upper structure because of un-uniform settlement of foundation,and soil deformation is an accumulation process with construction.Nevertheless,common calculating method for soil deformation does not take into account interaction between upper structure,foundation,and soil;and the influence that foundation settlement has on upper structure during construction process is not embodied yet.Therefore,formulas of settlement and internal force of upper structure is deduced,realizing method considering soil structure interaction and construction process is put forward.All these will contribute to the study of foundation's settlement and internal force of upper structure,soil reclamation and design of counter-deformation buildings in mining areas,and alleviation of damages caused by soil deformation.
Keywords:soil structure interaction  construction process  foundation settlement  internal force of structure
