| 摘 要： | 我国和俄罗斯等国的有关动力基础设计规范均规定机器基础的质量中心与基础底面面积形心之间的水平偏心距与偏心距方向的基底边长之比 ,对不同地基条件不得大于 3%和 5 %。对此进行了详细分析 ,指出了不同情况下偏心距对基础自振频率的影响 ,并初步提出了放宽偏心距限制的建议。

| Abstract: | The relevant codes of China and Russia s how that the ratio of mass eccentricity distance from the center of foundation b ase area to foundation side length in parallel with eccentricity direction is li mited to 3% or 5% under different conditions.The paper has studied the effect of mass eccentricity on natural frequencies of foundation under different conditions, meanwhile, put forward the suggestion on relaxing the limitation. |
