| 摘 要： | 在初始地应力场分析问题中,采用了多方程回归方法。该模型同时考虑了一组变量(包括自变量与因变量)之间的所有关系。在此基础上,采用逐步回归法进行计算,进一步提高了计算精度。由此,得到了回归效果更显著的初始地应力场。

| Abstract: | Initial in-situ stress field is analyzed with multiple variables and equations regression. Relationship of a group of variables including variables and dependent variables can be considered simultaneously in the regression. On the basis of the regression, progressive regression is used in order to increase fit precision, with which more obvious effect is obtained. |
