摘要
采用基于人工神经网络的边坡位移反分析方法，取得了三峡永久船闸开挖边坡多介质岩体的宏观等效弹性模量，并利用各层等效弹性模量进行了有限元正分析计算，预测了三峡永久船闸开挖边坡下一开挖阶段的应力及变形发展趋势。
This paper presents a backward analysis method of measured displacements on basis of artifical nerve networks. As its primary application in engineering, it has been used to determine the equivalent elastic modulus of multi medium rock mass of excavated slope of Three Gorges Project(TGP) permanent lock. Using these equivalent elastic modulus and EEM, the tendency of stress and deformation of newly excavated slope of permanent lock in the next excavation step in the same area was analyzed and forecasted.
