摘要： 探讨了地基附加应力计算中的误差形成原因，一题多解和组群现象，得出Ko 和4Kc允许误差在0.005以内或0.007以内，Kc在0.0012或0.0018以内，还讨论了KcKo的配套关系（规律）问题。

Abstract: The calculation error of additional effective stress induced by foundation loadings; based on different grouping and various solutions for one problem; are discussed in this paper. It is found that the error tolerances for parameters Ko 和4Kc are between 0.005 and 0.007. This paper further discusses the complementary relationships between Kc和4Kc and the related calculation formulas. These relationships are the basis of understanding the calculation errors.
