Stress analysis of subterranean hydropower plants during construction

Abstract

    Deeply-placed subterranean hydropower plants in natural environment must bear greatly complicated loads. The construction has changed the natural stress state, disrupted the initial equilibrium state and exerted impacts on load-bearing structures of subterranean plants. Contents introduced in this paper are the stress analysis of subterranean hydropower plants during construction taking the actual geological faults into consideration. Initial research results have shown an overall picture of actual evolution of stress change in the medium during construction stage.
