TBM法隧洞的开挖施工测量

Excavation,Construction and Survey for Tunnel with TBM Method

施工控制测量是隧洞贯通的根本保证,长大距离的地下洞室开挖施工,对贯通中误差要求很高,而线性的隧洞工程内部不利测量控制网的布置,采用高等级的仪器,正确的测量方法进行贯通中误差、平面测量、高程测量,可以确保TBM开挖方向,保证隧洞的贯通质量。

Construction control survey is the basic guarantee for the tunnel holing-through, the excavation and construction of underground cavern in long distance has high demand on errors for run-tunnel through. But, internal tunnel project in linear is not suitable for the layout of control network, adopting high-level instrument and correct survey method for holing-tunnel through, plane survey and elevation survey to ensure the excavation direction of TBM, so as to ensure the quality of run-tunnel through.
