铁路隧道裂缝的变形测量

The Measurement of the Displacement of the Railway Tunnel’s Fractures

铁路隧道受到损坏,出现不同程度的裂缝、变形,将严重影响到隧道本身的使用安全,这就要求测绘人员必须根据实际情况选择合适的测量方案来满足工程的需要。结合工程实践,探讨了铁路隧道裂缝变形测量的有关问题。

The fractures and displacements, which occur in the damaged railway tunnel, will influence seriously the safe use of the tunnel itself, so the mapping engineers are required to select suitable measuring scheme according to the actual situation to satisfy the requirements of the engineering. Connecting with the engineering practice, this paper probes into the fractures and displacements of the railway tunnel.
