地表沉降控制一直是城市地铁浅埋暗挖隧道施工的一个重点、难点、风险点。本文通过深圳市地铁工程中一段具有一定典型意义的浅埋暗挖隧道工程,阐述了控制沉降所采取的隧道内和地表施工措施,以期对类似工程施工提供些许可供借鉴的经验教训。
Control of surface subsidence has been a key, difficult and risk point in the construction of shallow buried tunnel of urban subway. In this paper, a section of shallow buried tunnel excavation project with a certain typical significance in Shenzhen subway project is elaborated, and the construction measures of tunnel surface and surface adopted for controlling settlement are expounded in order to provide some experiences and lessons for similar project construction.
