| Abstract: | Based on the combination of the elasto-viscoplastic finite element method and artificial neural networks,a model of back analysis of the mechanical parameters of slope is established.The intake slope of generator unit No.9 of Longtan Hydropower Project is studied,it is being excavated.Construction procedure and anchor measures are simulated effectively;the relative mechanical parameter of rock is back analyzed;the real time forecast of deformation and stability of the rock slope are realized by this model according to monitor displacements.Most of research results are taken as the references for the optimization of design and information construction in the practical engineering. |
