| 摘 要： | 首先分析了三峡工程船闸边坡有限元计算和现场监测的位移成果, 说明岩石边坡位移反分析必须考虑岩体的松动因素, 本构模型可以使用弹性模型;其次介绍了松动区的有关物理力学性质, 以及在计算模型中的考虑方法;最后以基于BP 网络和遗传算法的位移反分析模型反演了永久船闸边坡岩体及其松动区的弹性模量。

| Abstract: | Firstly the displacements both from field measurements and from finite element method are analyzed to demonstrate that the disturbed zones should be considered in the displacement back analysis of the ship lock slopes of the Three Gorges Project and that elasticity is the feasible constitutive relation. Secondly the mechanical and physical properties of the disturbed zones are introduced and the methods for considering disturbed zones are discussed. Finally the elastic moduli of both the primary rockmasses and their disturbed zones are back analyzed by an error back propagation neural network (BP network) and genetic algorithm based model. |
