摘要
基于地应力场产生的原因,建立了地应力场的数学模型.根据实测地应力资料,利用多元非线性回归分析的基本原理,得出了计算区域初始地应力场应力分量的回归公式.据此, 可以预测该区域范围内的地应力分布状况.
Based on the origin and nature of in situ stress, a mathematical model was built up. The regression equations of the six stress components were obtained according to measured results and the principle of multivariate nonlinear regression analysis. These equations are important for understanding the feature of the initial stress field in an area.
