Abstract：The effect of aging factors on displacement was studied on the basis of the survival regression model. Firstly, the numerical sequence of displacement data obtained by the original monitoring data were transformed to the “event status” sets {s(p)i|0, 1}. Secondly, the aging factors were divided into “months”, “quarters” and “years” , respectively. Finally, the “event status” sets are substituted into the survival regression model, and the effect on the displacement data was researched. The results show that the calculation results are slightly different with the different aging factors when calculating their effect on the displacement.
