摘要: Abstract Convergence monitoring of the drift or tunnel in construction and running stage is essential, especially case frequent human interferential activities. It useful to monitor convergence for engineering workers prevent collapse caused by excessive settlement. This paper introduces a continuous cross-section system which used control circular board, tilt sensor draw-wire displacement as data acquisition device. The system, can realize monitoring, easy installation, no artificial attendant, security vulnerabilities, interference normal drift, satisfy measuring requirement because its any frequency, little error, high accuracy that reaches 0.01 mm. using experience gold mine Shandong province verified it good at deformation cross-section.
