Description
Technical field
The method that the present invention relates to the Three-direction deformation of a kind of Deformation Monitoring seam both sides agent structure.
Background technology
Due to engineerings such as large-scale construction of structures engineering or subterranean tunnels in use, by periphery construction, naturally drop
Water, earthquake, blast etc. are artificial or the impact of natural cause, and the differential settlement occurred in various degree known from experience by foundation soil or the soil body moves
Moving, the agent structure of engineering can occur entirety or the sedimentation and deformation of local.For structural safety, in engineering design and construction process
In, all can be arranged as required to the movement joint of the types such as aseismatic joint, subsiding crack, expansion joint.When deforming, movement joint both sides
Structural elements in vertical and two horizontal direction generation Relative Displacement shiftingizations, the vertical changing of the relative positions (Z-direction phase para-position can i.e. occur
Move), the horizontal changing of the relative positions (X-direction relative displacement, the change in displacement of the i.e. first horizontal direction), level interval change (Y-direction phase para-position
Move, the change in displacement of the i.e. second horizontal direction).Monitoring means to the agent structure deformation of Engineering Structure Distortion seam both sides at present

Displacement) time, two horizontal displacement sensors to be set at deformation joint, a vertical displacement sensor, and by sensor two ends
It is separately fixed in the structure of movement joint both sides, catches the relative shift of movement joint both sides agent structure.2. by three displacements
Sensor is installed radially and stitches both sides in malformation, when structure deforms, by the angle between three sensors
With Sensor monitoring to data calculate, draw structure deflection in three directions.
Above-mentioned prior art is primarily present following two point defects: (1) for above-mentioned scheme 1., due to existing sensing
The mounting bracket of device is all integrally fixed in the agent structure of both sides, when there is the relative changing of the relative positions in movement joint both sides agent structure, and sensing
Device can occur systematic error, causes Monitoring Data to be made mistakes.As a example by only there is the X-direction changing of the relative positions, the horizontal position that deformation joint is arranged
Displacement sensor can occur stretching or contraction distortion, and the data monitored are X-direction sliding deformation amounts accurately, but simultaneously as
Y, Z two direction displacement transducer two mount points between position there occurs change, distance between mount point becomes big, displacement
Sensor there will be stretcher strain, and the display structure of mistake exists Y-direction and the Z-direction changing of the relative positions at generation X while the changing of the relative positions.In like manner,
When only there is Y-direction or Z-direction deformation, the displacement transducer in other two directions also can show and there occurs deformation.And occurring two
Or during the deformation in three directions, the data of sensor there will be bigger error, and then influence technique personnel are to structure detection number
According to accurate analysis.(2) it addition, the deformation that 2. 1. above-mentioned current art scheme and monitor three directions need to use three sensors
Being monitored three directions respectively, the data acquisition of three sensors needs to take three data channel on Acquisition Instrument.Simultaneously
Monitoring device takes up room the biggest, and after installation, the utilization to space can affect.

Movement joint both sides agent structure change in displacement in the X direction can be calculated according to the rotational angle of this double-shaft tilt angle sensor 2.
When movement joint both sides agent structure is subjected to displacement change in Z-direction, the first support 4 and the second support 5 are in Z-direction
On on the one hand be subjected to displacement change therewith, because sensor installing plate is contacted, further through connection with the second support 5 by trapezoidal key 22
Axle 8 contacts with the first support 4, result in sensor installing plate 7 run-off the straight so that the double-shaft tilt angle on sensor installing plate 7
Sensor 2 rotates around X-direction, and meanwhile, double-shaft tilt angle sensor 2 rotates around X-direction and drives metal sleeve 17 and metallic rod 16 1
Rise and rotate around X-direction, i.e. metallic rod 16 is rotated around connected installation axle 9, thus can be according to this double-shaft tilt angle
Sensor 2 calculates movement joint both sides agent structure change in displacement in z-direction around the rotational angle of X-direction.
When movement joint both sides agent structure produces displacement in the Y direction, the first support 4 and the second support 5 are in the Y direction
It is subjected to displacement therewith so that the displacement monitoring component 3 being positioned on the first support 4 and the second support 5 occurs stretching or shrinks, thus
Movement joint both sides agent structure can be obtained according to the stretching of displacement monitoring component 3 or contracted length and produce displacement in the Y direction.With
Time, when movement joint both sides agent structure produces displacement in the Y direction, the metal being connected with the installation axle 9 on the first horizon bar 4-1
Then there is the displacement of Y-direction along with the movement of the first support in bar 16 so that metallic rod 16 is sent out in the Y direction with metal sleeve 17
Raw relative displacement, now, metal sleeve 17 then remains stationary as, it is ensured that be arranged at the double-shaft tilt angle sensor on metal sleeve 17
2 will not rotate, it is to avoid when movement joint both sides agent structure produces displacement in the Y direction to double-shaft tilt angle sensor 2
Impact.
