| Abstract: |
| The modulus backcalculation of pavement structure is the foundation of nondestructive testing and evaluation of highway. Based on the characteristics of genetic algorithm and simulated annealing algorithm, a new approach, Genetic and Simulated Annealing Hybrid Algorithm, is put forward to backcalculate the elasticity modulus of pavement structure. Compared with the traditional genetic algorithm, the global convergence effect of this hybrid algorithm is enhanced by use of the Metropolis acceptance rule of the simulated annealing algorithm in the searching process. Some theoretical data and testing data are analyzed with this method and the results are compared with those due to other methods. The results show that this method is good in the global convergency, and the results of modulus backcalculation are stable and credible. |
