地铁工程的建设与发展为缓解城市公共交通、提高城市道路利用率奠定了基础。同时地铁工程的开展也为解决城市交通拥堵、提高城市地下空间利用带来了新的发展机遇。在进行地铁工程的施工过程中,由于开挖施工将扰动地下土地、造成地表及地铁地层沉降的发生。地铁地层沉降极大的影响了地铁行车的安全性,危害了地铁乘客的人身安全。针对这样的情况,加强地铁施工过程中地层沉降的控制与检测成为了现代地铁工程建设的重点。本文就地铁地层沉降控制与检测进行了简要论述。
The construction and development of the subway project laid the foundation for alleviating urban public transport and improving the utilization of urban roads. At the same time, the subway project has also brought new opportunities for development in solving urban traffic congestion and improving the utilization of urban underground space. During the construction of the subway project, the excavation and construction will disturb the underground land, causing the settlement of surface and subway strata. Subway settlement greatly affected the safety of subway traffic, endangering the personal safety of subway passengers. In response to such a situation, strengthening the control and detection of strata subsidence in the subway construction has become the focus of modern subway construction. This article briefly discusses the control and testing of subsidence in metro strata.
