Application Of Unequal Time Interval Grey Forecast Method On Tunnel Displacement Monitoring

unequal time interval, grey forecast, tunnel monitoring, displacement convergence

Displacement monitoring ( convergence displacement included) is the greatest meaning and the most usual monitoring item. But sometimes affected by some factors such as field engineering , every day’s data is hard to get. Unlike Ordinary Grey System and other forecasting method which can’t deal with such problem, Unequal Time Interval Grey Forecasting Method do more accurate imitation and more precise forecast, finally this method is well used in SanShiLiPu Tunnel’s displacement monitoring in NingXia.
