| Abstract: | The composition,layout type and access of adjustment reference for subsidence monitoring datum net of subway tunnel boarding are expounded,and the layout and observation method of subsidence survey point and differential settlement point in tunnel are briefly introduced.The mean spacing method of test for stability of monitoring datum net are discussed,and the method and principle of global analysis to tunnel subsidence according to characteristics of subway tunnel are introduced.Taking the tunnel subsidence monitor of Nanjing metro west elongation line as an example,the settlement situation,rules and genesis of tunnel construction are analyzed.Favorable conclusion is made,which provides a decision-making reference to project-managing department for reinforcing tunnel structure,foundation treatment and rebuilding strem. |
