| Abstract: | According to stochastic medium theory,the subsidence model of tunnel is established,and modified floating-coding GA(MFCGA) is put forward,in order to calculate parameters of the subsidence model.It not only has a rather high convergence speed,but also can obtain a whole exact solution of the global optimization problem.The results of its applications in the nonlinear model show that this method is practical,efficient and superior to other methods. |
| Keywords: | Tunnel engineering Modified floating-coding GA Subsidence model Optimization |
