For all long , however , they have been divided up in routine design that is taken at large by engineers , i . e . , the rigidity relation and deformation correspond thereof are not considered so that the deformation and displacement from foundation are neglected , which will result in errors neglecting the restrained function to the warp of foundation due to the rigidity of the upper structure and the secondary stress of the upper structure because of different settlement from the foundation 而长期以来，工程界普遍采用的方法是将上部结构、基础以及土体分割开来，不考虑各部分之间的刚度联系和变形协调，忽略了基础的变形和位移，从而忽略了上部结构刚度对基础翘曲的限制作用，以及基础的差异沉降对上部结构引起的次生应力，因而在安全性和经济性方面都存在缺陷。
