Abstract

In a previous paper by the authors, the definition, formulation and the necessary modifications to introduce the developed infinite elements into a finite-element code have been demonstrated. The performance of these elements has been verified for a number of infinite domain problems whose analytical solution already exist. Among the innovative advantages of the developed elements is its capability to deal with the problems requiring changing the decay origin position with different solution stages, mobile pole, without the need for model re-meshing. In this paper, the method of employment of the developed infinite elements in case of excavation problems, which may be extended to tunneling problems, as well as the necessary modifications required to the finite-/infinite-element code will be clarified.
