通过三维弹性有限元分析和单向标定实验，分析了盲孔法与通孔解的关系，着重研究了应变释放系数Ａ、Ｂ值，Ａ、Ｂ值随着孔深与孔径之比（ｈ／ｄ）的增大而增大，当ｈ／ｄ＞１．０～１．５时，Ａ、Ｂ值基本趋于稳定。而Ａ、Ｂ值与应力水平几乎没有关系。同时还提出，盲孔法计算可套用通孔公式，但深盲孔（ｈ／ｄ＞１．２）并不等价于通孔，只是在一定的测试条件下与通孔接近。 Through the three-dimensional elastic finite element analysis and unidirectional calibration experiments, the relationship between blind hole method and through-hole solution was analyzed. The strain release coefficients A and B were studied emphatically. The ratio of hole depth to hole diameter (h / d) increases and increases, when h / d> 1.0 ~ 1.5, A, B values ​​basically stabilized. The A, B value and stress level almost no relationship. At the same time, it is also proposed that the blind hole calculation can be applied to the through hole formula, but the deep blind hole (h / d> 1.2) is not equivalent to the through hole but only approaches the through hole under certain test conditions.
