Research on the prediction of stable displacement and unstable time on highway tunnel
XU Lin-sheng · Journal of Chongqing Jiaotong University · 2005
According to the features of displacement-time curves, we use grey Verhulst model of creature increase to forecast the stable displacement and use Verhulst inverse-function model to forecast the unstable time of highway tunnel surrounding rock. Examples are applied to check and prove the prediction models,the construction is controlled.
