Description
Technical field
The invention belongs to hazards control field, and in particular to a kind of intelligent crag collapse rock-fall disaster monitoring system
And method.
Background technology
China is mountain region big country, and mountain and hill accounts for territory total area more than 2/3, with China Higher level highway and railway
Quick to build the high speed development built with Mountain Urban Area, massif high cutting-slope quantity is increasing and the highly increasing, gradient is got over
Come steeper, geological security problem also increasingly highlights.Collapse rock-fall disaster easily occurs for highway, Along Railway mountain area, and this calamity
It is harmful have it is sudden, it is both irregular to follow, it is also difficult to predict.May so side slope crag collapse rock-fall once occurs
Cause huge harm.For the collapse rock-fall geological disaster of crag, the monitoring technology of existing crag collapse rock-fall geological disaster
Mainly have and be divided into two kinds, one kind is to dispose various types of sensor in side slope, and the stability of side slope is monitored；
Another kind is to set in the mountain area border region of railway, Highways ' and can intercept the passive soft protecting net of falling rocks, and anti-
Corresponding sensor is installed, to realize the real-time monitoring to hillside Rolling Stone and effective early warning of rockfall hazards, so as to drop on protecting wire net
Low Rolling Stone invades limit Loss of Life and property to caused by railway, highway transportation.
Based on above two method, specifically there are three kinds of specific practices, but there is it to be difficult to the technical problem overcome：
Pulling force sensor is installed in side slope, rolled by monitoring the situation of change in crack to predict when avalanche occurs for crag
Fall.Though this way can accomplish effective early warning, construction environment is poor, and unsafe factor is in the majority, in work progress, due to applying
The influence of work technology, the stability of original side slope can be all destroyed to a certain extent.
Inclination sensor is installed on the column of soft protecting net, each sensor connects composition series connection closure electricity by wire
Road, the angle of inclination by monitoring the offset of soft protecting net either column tumbles determining whether to occur crag or mudstone
Stream etc. geological disaster, when by it is large-scale tumble geological disaster when, closed circuit disconnect, alarm mechanism start working, send early warning.
Although this method has automatic monitoring, automatic alarm, service is provided independent of third party, cost is low, easy to spread, has one
The advantages of fixed economic benefit.But this monitoring method is easily influenceed by extraneous factor, wind and human factor are likely to
Soft protecting net is set to shift, closed circuit disconnects work, it is easy to judges by accident, monitoring reliability is low.It is moreover, small-sized
Crag avalanche, which tumbles, can not make column run-off the straight, and alarm mechanism would not send early warning, and accuracy of detection is relatively low.In addition, work as
Alarmed after early warning is sent, it is necessary to artificially go to release so that Monitoring Data does not have continuity, it is impossible to accomplishes to monitor in real time.Moreover
Monitor and alarm system is complicated, it is necessary to largely lay circuit, and it is very big to lay line construction difficulty in physical features complex region.This monitoring
The electric supply system that technology uses is chemical cell, to ensure that monitoring system does not influence its normal work because of dead battery,
Not timing is needed to change battery, scene needs rear personnel, it is necessary to substantial amounts of manpower.
Fiber grating pulling force sensor is concatenated with protection network anchor cable using the characteristics of fibre optical sensor, or by optical fiber light
Grid vibrating sensor is fixed on anchor rope centre position, or fiber grating bend sensor and supporting rope on protection network are tied up
Fixed, the stressing conditions restricted on the net by monitoring protection judge the generation of geological disaster.Although fiber-optic grating sensor monitoring technology
With not influenceed by electromagnetic field and electromagnetic radiation, it is monitored, and quality of materials is light, and small volume, optical-fibre communications is not charged, uses peace
Entirely, the advantages of use environment temperature range is wide, resistant to chemical etching, and service life is long.But FBG monitoring technology is being applied
When also there is certain deficiency, performance is in the following areas：(1) fiber grating is using the wavelength of grating as sensing media, is passed through
Wave length shift perceives the change of extraneous physical parameter, and fiber grating directly reacts the change of strain and temperature coupling, it is necessary to enter
Trip temperature compensates, and monitoring sensitivity and resolution ratio is not high, and signal monitoring reliability is low.(2) principle of reflection based on fiber grating,
Its Monitoring Data is set not have continuity, it is impossible to accomplish to monitor in real time.(3) signal demodulating system of fiber-optic grating sensor is answered
It is miscellaneous, it is expensive.(4) fiber-optic grating sensor is typically mounted on the pull bar of protection network both sides or on upper supporting rope, for
Small rockfall hazards, the interception function through stone blocking net, power can not be delivered to supporting rope and draw anchor on, be placed in draw anchor on and
Sensor on upper supporting rope at all monitoring less than there is falling rocks to tumble.(5) data monitored by analyzing fiber-optic grating sensor
Foreign body intrusion can only be determined with, it is impossible to it is accurate to judge it is animal or falling rocks, easily judge by accident.(6) optical fiber belongs to glass system
Product, examining tensile behavior is low, when by the pulling force of very little, will be broken.Based on the above-mentioned of fiber-optic grating sensor monitoring technology
Shortcoming, not popularization and the popularization on a large scale of optical fiber grating sensing monitoring technology, current vast mountain area is taken or tradition
Monitoring technology.When falling rocks volume is excessive or during excessive velocities, all there are the possibility that falling rocks breaks through protection network, this is just needed
Measuring error is carried out to stone blocking net, traditional monitoring technology not can determine that where stone blocking net is damaged, and can only have artificial
Measuring error is carried out to stone blocking net.Stone blocking net is typically located at highway, and on the upper level of railway both sides, physical features is rugged and rough, car
It can not travel.When manually removing Measuring error, can only carry out on foot, Measuring error is wasted time and energy.Stone blocking net is continuous several simultaneously
Km is, it is necessary to often locate all to check, without specific aim, in maintenance and inspection, quantities is big, it is necessary to substantial amounts of manpower, add through
Ji input.
The content of the invention
Tumble existing for monitoring technology that Monitoring Data reliability is low for existing generation crag avalanche, it is impossible to accomplish complete in real time
