Abstract: The factors affected on prestress losses of unloading rock mass such as stress state of rock mass, rock mass property, rheology of rock mass, the time of prestress action, steel fiber relaxation, construction quality, anchor cable structure, environment change in long time are discussed; the mechanism of prestress losses with factors is put forward; and the coupling between different factors and prestress losses is discussed too. The relevant conclusions are drawn.

Key words: unloading rock mass, prestressed anchor cable, prestress losses
