| Abstract: | Combining with the multipoint displacement meter's measurements for Tianhengshan Tunnel of Ha'erbin,by using MATLAB BP neural network toolbox and ANSYS 10.0,and based on the finite element method for structural analysis,the artificial neural network training samples for the relationship between the different mechanical parameters of surrounding rock and the surrounding rock's deformation of tunnel are set up by positive direction analysis.And then,combining with the measured values of the tunnel's surroundi... |
