ZHOU Yong-jiang1, HE Si-ming2, YANG Xue-lian1. Study on prestress loss of anchor cables under long-term loading[J]. 2006, (8): 1353-1356.DOI: 10.16285/j.rsm.2006.08.025.
The pretress loss of anchor cable is the key cause induced the anchor structure failure;based on investigating all influencing factors
a method for calculating prestress loss is put forward;the influencing factors of prestress loss of anchor cable under long-term loading are analyzed;the relaxation model of steel strand
rheological model of rock as well as creep damage model of grouted material are put forward respectively;and using these theory to predict the prestress loss of anchor cable.There are the significant-sense to design and manage anchor cables.
