| Abstract: | The ground surface settlement due to tunnel excavation and ground surface rising due to squeezing by shield is considered as a stochastic process; and the stochastic medium theory is applied to predicting and analyzing the ground settlement in longitudinal surface due to tunnel construction; and the corresponding calculation formulas are derived. An example of case history shows that the prediction method developed can reach good results and has some practical value. |

| Keywords: | tunnel construction by shield ground settlement in longitudinal surface stochastic medium theory |
