Abstract
With the development of economy, the urban population has increased dramatically; in the process of urban construction, more and more tunnels are built in order to facilitate people’s life. Tunnel construction will inevitably cause land subsidence; the buildings on the ground and the normal use of underground pipelines will be affected when the subsidence reaches to a certain extent. The land subsidence has to be predicted in order to reduce the bad influence on the surrounding environment; first, study the theory of land subsidence due to tunnel excavation, and establish the finite element numerical simulation model for land subsidence caused by tunnel construction; then, make comparative analysis on the land subsidence caused by tunnel construction under the two different conditions of no drainage and drainage; finally, make comparative analysis on the main factors causing land subsidence of tunnels and confirm the influence degree of each factor. Through the simulation analysis, present the finite element simulation model and correlative conditions of tunnel construction on the ADINA platform, and find out the range and extent of influence from different factors on land subsidence, which is of great significance for controlling land subsidence, protecting buildings on the ground and underground pipelines in the process of construction.
