| Abstract: | Application of six unconstrained optimization methods for back analysis of visco elastic displacement in the roadway are discussed. With aspects of selection of initial point of parameter, convergence speed, convergence accuracy and reliability, it is found that the damped least square method is the best method for back analysis of visco elastic displacement. |
