Construction Monitoring of a Shallow Tunnel in the Lefortovo District of Moscow

Results are cited for analytical prediction of the influence exerted on surrounding buildings and structures by the construction of a shallow tunnel installed by the open-pit method. Two sections of the route along the third transportation beltway in the Lefortovo District, for which three-dimensional mathematical models of the construction were developed, are examined. Results obtained indicated the negligible effect of the tunnel's construction on existing buildings and structures, and are in good agreement with data derived from geodetic observations. The condition of the tunnel structures was monitored using monitoring-measuring equipment installed at three sites along the route.
