摘要
利用应力函数及有限元方法，建立用待定参数表示的初始应力场，通过和实测应力值比较，用优化方法计算待定参数值，算得初始地应力场．该法能考虑岩体结构、岩性及地形等因素对初始应力场的影响．实际工程算例表明，这种方法具有良好的实用价值．
The initial stress field expressed by the parameters to be settled is established using thestress function and FEM. The initial geostress field is calculated by comparing with the measuredstress value and using the optimum method to calculate the value of papameters to be settled.The proposed method can take the influence of rock body structure, rock property andgeomorphologic factors on the initial stress field into consideration. The calculation exampleshows that this method has good applied value.
