Abstract
This paper focuses on discussing the parameter identification techniques in geotechnical engineering. Firstly, the general formulation of the parameter identification process is presented. Secondly, the problem of identifiability is discussed and illustrated by an example of identifying the initial damage parameters of a damage model for jointed rocks. Then the algorithms of designing the optimal layout of displacement measurements are proposed, based on the analyses of the well-posednesses of the parameter identification processes with the Gauss-Newton method and the Complex method, respectively. The validities of these algorithms are proved by some academic and applied engineering examples. Finally, the advantages and drawbacks of the gradient-type methods and the direct-search methods are carefully compared.
