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。
Using the method of back analysis of slope displacement based on artificial neural network, the macroscopic equivalent elastic modulus of the multi-media rock mass of slope excavation in the permanent shiplock of the Three Gorges Project was obtained and the finite element method was used to calculate the equivalent elastic modulus , Predicts the development trend of the stress and deformation of the next excavation stage of the permanent shiplock of the Three Gorges.
