Reduce.Disturbance caused by excavating leads to adjacent buildings, facility ground and the relative settlement on basis in disturbed area.Cause
This, the underground engineerings such as foundation pit, tunnel, mining generally require the relative settlement to adjacent buildings, facility ground and basis and carry out
Monitoring.There are many insufficient and defect, such as inclinators can only monitor a point, largely arrange measuring point for common monitoring method
Poor continuity between cost is high and different measuring points data；Method is measured based on geometric coordinate to be settled (such as measurement of the level), it is past
It is past to be monitored precision, restriction of monitoring condition etc..In engineering practice, it needs one kind to can be applied to underground engineering construction to cause
Adjacent structure object relative settlement monitoring precision height, low cost, the method that can continuously measure.
Summary of the invention
Technical problem solved by the invention is to provide a kind of relative settlement accumulation measurement method and device, on solving
State the problems in background technique.
Technical problem solved by the invention is realized using following technical scheme: a kind of relative settlement accumulation method for measurement
And device, comprising the following steps:
(1) three point determines a plane, determines monitoring criteria.Utilize basic geometrical principle: 3 points determine a plane,
It basic top surface can be according to monitoring condition, 1 and 2 observation points of arranged for interval, longitudinally adjacent 3 observation points, one triangle of composition
The top surface of shape, i.e., 3 observation points constitutes a plane of vision；
(2) periodic observation inclination angle senses measurement system monitoring criteria face and plummet by the inclination angle of acceleration of gravity principle
The variation of face angle, using acceleration of gravity formula high-precision tilt angle sensor and its reading, transmission, display system, observation monitoring
The variation of datum level and the plummet direction angle of cut；
