Abstract：Research purposes ： With the development of urban construction， underground tunnel brings social and economic benefits in various engineering fields. At the same time，the impact of shield construction is also increasingly prominent. The research on shield tunneling of 202 bid section of Dalian metro is carried out to analyze the influential effect of surface settlement by three - dimensional finite element， combined with geological conditions and on - site monitoring data.
Research conclusions: The results show that ： (1) The V - shaped lateral surface subsidence is large above the shield， and it decreases on two sides. (2) The vertical surface subsidence is S - shaped，that is the ground heaves in the front of excavation face，it sinks in the back of excavation face，and it is stable in the certain distance. (3) The research results of this paper can monitor metro shield tunnel in the construction.
