Through the analysis of the convergence monitoring technology and its limitations, the improvement of the traditional measurement technology by extensometer was put forward. A new convergence monitoring pile is introduced and so are the struc-ture, installation and operation method, the new scheme has the advantages of convenient operation, quick measuring and high measurement precision. The monitoring of the convergence of above 10 m measurement distance can be realized. Accordingly, we put forward the convergence measurement scheme for the tunnel with large section and underground cavern with large span, and obtain the actual measurement results, which prove that the new convergence monitoring pile can meet the requirements of meas-urement accuracy.
