| Abstract: | The uneven settlement of highway can bring great security risk for vehicle operation. Settlement observation and prediction of highway is necessary means to protect the security operations of highway. This paper adopts time-series method for settlement prediction of highway and analyses the theory of modeling steps, parameter estimation and adaptability of time series model. We can obtain prediction results and its accuracy by programm calculation. Compared with the traditional method--hyperbola method, we find that time serial method has higher prediction accuracy and better engineering practicability. |
