Joint back-analysis in mining subsidence

Résumé

Subsidence due to underground mining excavation is a typical limited data problem. For a preliminary identification problem, elastic rockmass and joint behavior is supposed, and a method based on minimization error of constitutive law has been used. In this subsidence problem, joints behaviour appear to have a great importance. This inverse method is proved to be efficient and with a rapid convergence. Finaly, selection and position of measuring points are analysed.
