  Analysis of the Influence of Metro Tunneling on Building Settlement

  Although the characteristics of ground settlement without buildings have been defined, but further research is still needed for the characteristics of settlement with buildings, and such research has more theoretical significance and engineering application value. Targeting at the specific strata and shallow foundation buildings, FLAC 3D is utilized to establish the three-dimensional numerical models and conducted a comparative study of the characteristics of strata and building settlement under two conditions, i.e., without or with buildings, so as to reveal the characteristics of strata and building settlement at different positions of strata and buildings and to discuss the safety control standards of building settlement caused by metro tunneling. Then, a project example was analyzed and showed that the numerical simulation was consistent with the measured results, which provides technical support for the safety assessment of metro tunneling.
