摘要

The proposed concept of perturbed finite-element sensitivity analysis can be applied to complex cable configurations and boundaries to assess the effect of variations of various soil and boundary parameters. The technique is applied to both design phase and operational aspects of power cable buried in a complex media of soils, heat sources and sinks as well as variable boundary conditions. The applicability and usefulness of the developed methodology via applications to several test and actual cable systems under different loading, soil and atmospheric conditions is exploited in this paper.
