【摘要】 本文根据上部结构和地基基础相互作用的机理,提出了发挥上部结构抗弯刚度和抗剪刚度的有限性,指出了发挥抗弯刚度的上限。文章还分析了结构物以弯曲变形为主转化为以剪切变形为主的变化规律和转化条件,在此基础上提出了基础内力计算的两个阶段,并给出了计算公式及计算例题。更多还原

【Abstract】 Based on the mechanism of interaction of superstructure, foundation and soil, the development of the finiteness of bending rigidity and shear stiffnes of the superstructure is suggessted, and the upper limit of bending rigidity development is pointed out. The conditions that dominate the structure changing from bending deflection to shear distortion and the law of transformation are also analyzed. Based on that, two stages with corresponding formulas for calculating the internal forces of the foundation are put forward and an example is given.更多还原
