【摘要】 利用ＢＰ神经网络对我国四个金属矿山共３８个测点的地应力测量结果进行了分析。结果表明，地应力值随岩体的埋藏深度和弹性模量的增加而增大，但地应力与岩体弹性模量的关系远不如它与岩体埋藏深度的关系那样有良好的线性关系。更多还原

【Abstract】 By means of artificial neural networks,this paper makes an analysis of the results of in situ stress measurements.The result of analysis shows that the magnitude of in situ stress has the trend to increase with the increasing of the depth and the elastic module of rock mass,but the relation between the in situ stress and elastic module is not so close as the relation between the in situ stress and depth.更多还原
