Abstract

Abstract:

Taking the construction of Xiongmao HuandaoAnding Road Tunnel on No.10 line of Beijing Metro as an example, the authors mainly introduce the construction technology adopted in complicated conditions, such as tunnelling under commercial buildings, excavation under existing tunnels, tunnelling in waterrich ground and near electricity tunnel. The above difficulties have been successfully solved by pipe well dewatering, vacuum dewatering, advance treatment of the buildings and presupport of the tunnel. This paper can provide reference for similar projects in the future.
