Following several mode is had for measuring tunnel vault sedimentation in current industry:
1. adopt steel ruler and spirit-leveling instrument to measure Vault settlement: the method mainly at monitoring section vault measuring point place, tunnel a pre-buried buckle measure stake and hang steel tape, observe its reading obtain Vault settlement amount with precision level.The method is mainly used in manual measurement, and data volume is little, and operation easier is large, labour intensity high, and the possibility not possessing automatic measurement.
2. adopt total station survey Vault settlement: the method mainly installs a common reflection plaster at monitoring section vault measuring point place, tunnel, utilizes total powerstation to record measuring point three-dimensional coordinate, by measured value coordinate is drawn Vault settlement value with the comparison of initial value coordinate.The method exist apparatus expensive, cannot Real-time Obtaining to change data.
3. adopt convergence gauge to measure Vault settlement: the method mainly arranges a buckle at both sides, tunnel abutment wall and vault place and surveys measurement stake, form triangle and arrange measuring point, then convergence gauge is utilized to record the Atria bar length of side of 3 compositions respectively, and conversion draws the height of first three dihedral single, by drawing Vault settlement value with the comparison of initial delta high level.Also it is little to there is data volume in the method, and operation easier is large, labour intensity high, and the possibility not possessing automatic measurement.
4. adopt laser distance measurement method: laser displacement sensor has the advantages such as good directionality, measuring accuracy is high, range finding is far away, antijamming capability is strong.
By consulting available data, current laser displacement sensor in automatic monitoring, is mainly used in clearance convergence monitoring in tunnel.
