Background
The tunnel monitoring measurement is one of three major elements of the new Austrian construction, and the tunnel construction carries out informationized construction by monitoring the measurement result, so that the self-bearing function of surrounding rocks is utilized to the maximum extent, and the tunnel construction is in a dynamic management system. Specifically, before the construction of tunnel engineering, the surrounding rock mass is in a stable ground stress environment, the excavation of the tunnel destroys the balance state of the original ground stress of the rock mass, and the tunnel surrounding rock reaches a new balance state again through the self-stabilization of the tunnel surrounding rock and the support of the support structure. The tunnel construction monitoring measurement refers to the monitoring of deformation and stress states of surrounding rocks and supporting linings by using various instruments and tools in the tunnel construction process, so that the following purposes are achieved: (1) and according to the measurement information, early warning of dangerous cases is carried out so as to take measures in time and avoid accidents. (2) The method has the advantages that the deformation development trend of the surrounding rock and the support of the tunnel is known, the stability of the surrounding rock is judged, and the final stabilization time of the surrounding rock of the tunnel is predicted, so that a reasonable construction sequence and the construction time of the secondary lining are arranged. (3) And (3) checking construction pre-design, and adjusting support parameters and a construction method to ensure that the design and construction are more economic and reasonable. (4) The measurement result of the existing engineering can be directly applied to subsequent similar surrounding rocks and also accumulates reference data for other similar engineering.
