Before waiting perforation, it will repeatedly show staged and rise by speedup, slipping property integration rheology, process is monitored in actual tracking
In, double coupled aging curves are also repeatedly presented, at this point, total calculate can also be used to differentiate that actual horizontal displacement deformation monitoring is bent
Whether line enters double coupled aging curves.
Total calculate divides two methods：
1) ξ=0, by 4 points of total computational methods；
2) ξ ＞ 0, by 5 points of total computational methods.
Total result of calculation differentiates：
1) calculation procedure then needs to judge y without solutionz、yqWhether assignment meets threshold value requirement.
2) if calculation procedure has solution, but tfTo violate time series forecasting value, both predicted value tfDate is less than tracking and monitoring day
Phase, it feeds back the integration rheology that sliding block is under non-constant load power drive, and development trend or stabilize is rested, or into
Enter double coupled aging periods.
3) if calculation procedure has solution, but predicted value tfDate farther out from the tracking and monitoring date, then in can doing, long-term forecast
Development trend refers to, and continues trace analysis.
4) if calculation procedure has solution, and predicted value tfDate is close from the tracking and monitoring date, should encrypt tracking and monitoring frequency
Rate, it then follows unstability creep period tfPredicted time is constant and does trace analysis from fitting characteristic.At this point, identification module to receive mould
