説明
In this paper, the methodology associated with deterioration forecasting of ground anchor based on results of visual inspection and lift-off test is presented. In detail, the deterioration process of ground anchor is modeled by using not only Markov chain process but also Weibull hazard functions. First, based on results of visual inspection and lift-off test, the soundness of ground anchor is classified into six ranks, and threshold for survival/damaged is set. Secondly, the survival probability of ground anchor is calculated by using Weibull hazard functions. Based on the proposed model, the prediction of future states of ground anchor is conducted. Finally, in order to make a study on the differences of the deterioration process between Weibull hazard model and Markov chain model, the simulation results predicted by two models are compared.
