Abstract Ground surface settlement induced by tunneling will affect the surrounding environment. Taking into account the problem of excessive ground settlement，analysis of field measurements of a Qingdao metro station is conducted to acquire empirical estimations of relevant characteristic parameters. First，according to the obtained settlement trough width and soil loss rates，the fitting curve of ground surface settlement trough was obtained using Peck method；and the recommendation of settlement trough width formula is given. Second，the fundamental ground surface moving parameters are obtained by using inverse analytical method based on ground surface measurement data of initial excavation．Furthermore，by using the scaling method，the ground surface moving parameters of the further excavation can be obtained，and eventually the ground surface movement of the whole tunnel due to the excavation can be predicted. Finally，the difference of the results of the two methods is obtained based on comparative analysis. In order to verify the correctness of this conclusion，impact angle caused by tunnel excavation of some cities in China is analyzed and converted into settlement trough width for comparison with existing achievements.

Key words： tunneling engineering metro station ground surface settlement ground moving parameters analytical method
