Abstract
The metro running intervals with more and more existing constructions put an inevitable influence on the existing construction foundation. In order to control the impact to certain limits, it is necessary to adopt effective technical measures before construction. This thesis analyzes the effect of isolation piles in controlling building deformation during the tunnel excavation by using the finite difference software FLAC3D, which takes Beijing subway line eight as an example and the construction conditions are divided into no reinforcement measures and applied isolated piles. By the contrast analysis, isolation piles can effectively control the building deformation through stress isolation and building deformation can be accord with requirement of standard, then to ensure the safe use of the building. In addition, this thesis can give references for the same kind of tunnelling construction in the future.
