| With the development of our country's economy, the population in cities increasing rapidly, more and more tunnels are used in order to reduce the influence to people's natural activities during the city constructions. The ground settlement induced by tunnel construction is inevitable, it will affect the regular service of the buildings on the ground and the pipelines underground when it is in certain extent. To reduce the adverse effects on the around environment, it must forecast the ground settlement. And with the rapid development of the computer, it is popular to do the numerical analysis using the finite element software to forecast the ground settlement induced by tunnel construction.Basing on correlative theories, it adopts the finite element software ADINA to do the numerical analysis on the tunnel construction, simulating the ground settlement induced by tunnel construction, analyzing the influence of correlative factors to the ground settlement under different conditions.Firstly, the theories about ground settlement induced by tunnel excavation are researched, the finite element simulation model about ground settlement induced by tunnel construction is built; secondly, constitutive models of soil body that common used are analyzed, the ground settlement induced by tunnel excavation under different models is compared and choose a better one to do the simulation; thirdly, the ground settlement under drained and undrained are compared; lastly, the main factors that affect the ground settlement are analyzed and got the extent of the influence of different factors.Though the simulate analysis, the finite element simulation model and correlative conditions of tunnel excavation under ADINA are given, the extent and the range of the influence of different factors to ground settlement are got. It will have important significance to control the ground settlement in order to protect the buildings on the ground and the pipelines underground during the construction.
