Description
Technical field
The invention belongs to Tunnel Engineering field of measuring technique is and in particular to a kind of intelligent laser response formula convergence monitoring
System and measuring method.
Background technology
Tunnel convergence measure be shotcrete bolt construction method construction in must survey project.After tunnel excavation, surrouding rock stress will be divided again
Cloth.In digging process, peripheral rock and supporting will be deformed, and this deformation is country rock and the change of supporting mechanical behavior is the most direct
Reflection.When surrouding rock stress tends to balance, peripheral distortion tends towards stability, and this change procedure is referred to as " convergence ".Tunnel inner surface
Convergence can be recorded by special measuring instrument.Observed by periphery displacement, vault sinking and horizontal convergence amount can be measured
Size and development, thus can differentiate that tunnel surrounding is whether stable, also can differentiate that support work state and construction method are simultaneously
No reasonable.
Tunnel cross-section measurement is one of important procedure of constructing tunnel.Mainly have following several at present in tunnel cross-section measurement
The mode of kind：
1st, Ba Saite collective system：This system is by multiple bar elements（One long and one short be combined into a pair
Bar element）Mutually hinged from beginning to end be arranged on section surrounding to be measured, constitute a measurement ring, bar element is built-in a kind of special
High accuracy electrolyte obliquity sensor, a pin joint of the long galianconism of each pair is fixed with tunnel wall phase by fixture, another
Pin joint is to float.When tunnel wall deforms, the several fixing points in deformed area must be made to produce（Space）Displacement,
Drive related long galianconism activity, that is, long galianconism occurs angle change, is at this moment separately mounted to the obliquity sensor on long and short arm
This small angle change just can be measured, if tunnel wall many places deform, often place's deformation to the effect of long galianconism is
Superposition idol, i.e. the change of obliquity sensor perception is total change, can according to the length of change of pitch angle and each accordingly long galianconism
To calculate the displacement of each fixing point, refer again to the coordinate in each fixing point home position it is possible to obtain a fixing point after change
Physical location, as long as there being enough fixing points, the line of each moment each fixing point just can approximately represent tunnel wall
Contour line, Bassett collective system is a kind of high accuracy, the system of automatic monitoring tunnel deformation.Whole system is automatic from data
The display collecting result of calculation fully achieves computerization.But this system is relatively costly, monitoring point is installed also very multiple
Miscellaneous.
2nd, convergence gauge is adopted to measure empty convergence in tunnel：It is characterized in completing to tunnel wall point-to-point transmission horizontal range
Deflection measurement, measurement of vault sinking and heave displacement etc., this measurement method precision is reliable, but this kind of side
There is the shortcomings of measurement data is little, and operation easier is big, labor intensity is high in method, need work on platform truck for large cross-section tunnel
Make, operation inconvenience relatively.
3rd, electronic total station is adopted to measure：The method buries retro-reflective targets as measuring point on the cross section of cavern, and every two
Become survey line between individual measuring point, erection electronic total station at measuring point can observed, measuring the three-dimensional coordinate of measuring point, public according to distance
Formula calculates the three-dimensional distance between each two measuring point, the three-dimensional distance value that the three-dimensional distance value that same period time does not record was recorded with first time
Difference be survey line between this two measuring point convergency value.Need not be every time close to measuring point during this method measurement, electronic total station is permissible
Freely it is arranged on the place that can observe measuring point, without forced centering, measurement data can record automatically, can easily adopt
Computer carries out post processing, realizes fast monitored, rapid feedback with guiding construction, but there is also instrument and equipment costliness, needs
Want periodic measurement, and real-time delta data can not be obtained.
4th, adopt laser distance measurement method：Laser has good directionality, range accuracy height, romote ranging, strong antijamming capability etc.
Advantage, carries out tunnel survey by the way of laser ranging, obtains in recent years more and more widely should in tunnel cross-section measurement
With.
By inquiring about available data, mainly or for tunnel is single broken what tunnel cross-section laser measurement adopted at present
The measurement of face convergency value is it is impossible to reflect the situation of convergence in a certain section of region in tunnel comprehensively.In addition existing laser measurement sets
Adopt the direct illuminating method of laser or the methods such as reflecting prism, reflecting piece, laser direct irradiation are installed at measured point for usual
Method is different due to tested surface material, and reflecting effect is bad, certainty of measurement is affected larger；Reflecting prism, reflecting piece etc. are installed
Method can only passively receive laser beam, and after the reflecting prism installed, reflecting piece deform with tunnel convergence, original position becomes
After change, typically common laser range finder cannot Automatic-searching reflecting prism, the position after reflecting piece deformation, thus causing to measure
Inaccurate, precise decreasing.
In a word, all also there is the respective defect of itself it is difficult to real realize in above four kinds of measuring methods to tunnel convergence
Requirement to the accuracy of tunnel convergence DATA REASONING, verity, real-time and convenience.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, and design one kind is be applied to the engineering constructions such as tunnel, foundation ditch
Automatic measuring measures size and the changing value of vault sinking and horizontal convergence amount, thus can differentiate whether tunnel surrounding is stable, simultaneously
Also support work state and construction method can be differentiated whether rationally, monitoring for safety for tunnel engineering provides a kind of complete tunnel many
