Description

technical field [0001] The invention relates to a system in the technical field of tunnel engineering monitoring, in particular to a subway tunnel section deformation detection system. Background technique [0002] For the detection of tunnel convergence deformation, traditional monitoring is mostly carried out by manual periodic monitoring. Due to the long observation time and limited observation period and frequency, this method is not suitable for tunnel operation. At the same time, with the improvement of analysis requirements, the tunnel health monitoring system during the operation period needs to have long-term use, fast, automatic monitoring and other functions. Can no longer meet the needs of the project. [0003] Commonly used detection methods at home and abroad: manual section measurement (convergence gauge), total station measurement, optical fiber measurement. Contents of the invention [0004] The purpose of the present invention is to overcome the deficie...
