【摘要】 本文应用三维有限元拟会方法，根据实测地应力资料，对某金矿的地应力场分布规律进行了研究。提出了结构面结点偶对分析原理和方法，用以正确模拟断层对地应力场分布的影响。分析表明，计算结果与实测值接近程度非常好，说明通过三维有限元拟合方法建立的矿区地应力场分布模型具有较高的精度。更多还原

【Abstract】 This paper introduces a regressing technique with 3-D FEM analysis to determine originalstress field based on in-situ stress measurement at limited points in a gold mine. In order to correctly imitatethe influence of a main fault on stress state in the mine, a nodal coupling model was developed. A good agreement between the regressing value and that actually measured indicates that the regressing technique iseffective.更多还原
