LI Jian-lin, DENG Hua-feng, HUANG Jian-wen, et al. Analysis of factors affected on prestress losses of unloading rock mass[J]. 2005, (S1): 292-295.DOI: 10.16285/j.rsm.2005.s1.069.
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.
