Description

Along Railway rockfall monitoring and alarming system
Technical field
The utility model relates to field monitoring equipment, signal processing system and monitoring and alarming system, more specifically, relates to field monitoring equipment, signal processing system and monitoring and alarming system for the Along Railway rockfall.
Background technology
Rockfall, as a kind of shallow table section failure mode of side slope especially high gradient slope, is one of serious geologic hazard.It is sudden strong, and randomness is large, and speed is fast, occurs fiercely, is the emphasis in the slope project prospecting always.Because the Dangerous Rock Body that forms the collapse rock-fall disaster is distributed on high gradient slope more, administer will expend huge manpower and materials fully from source, be more at present to take to cause the front falling rocks safeguard procedures of calamity.Falling rocks is that a kind of multiple geologic hazard ,Gei highway in China mountain area, railway construction and operation and mountain area people's lives are brought huge harm.I am subject to various factors by mountain road both sides massif, and the rock phenomenon of falling happens occasionally, and gently makes railway and vehicle suffer slight breaking-up, heavy road is interrupted, and to transportation by railroad, bring heavy losses; What is more, and the enormous impact energy serious threat of falling rocks is to people's life security, and its extent of injury is not second to geologic hazards such as rubble flow, landslides.Traffic safety and passenger's life securities such as railway, highway in the geologic hazard serious threat.Mountain railway particularly, once disconnected road occurs, thousands of passenger is detained other places, can not arrive destination, normal production, orders of life also are broken, and to social stability, bring enormous pressure on time, bring also to traffic operation department and passenger simultaneously and be difficult to the indirect economic loss of estimating,, actively take measures, various geologic hazards are carried out to monitoring and warning as far as possible great profound significance and impact for this reason.
Railway rockfall monitoring and alarming system technology, be mainly concerned with the foreign matters such as rockfall geologic hazard disaster prevention safety monitoring and warning system, rockfall and invade automatic monitoring technical, the transmission technology research of disaster prevention and alarm system data monitoring and rockfall disaster prevention safety monitoring systems technology detailed rules for the implementation and safeguard use management method etc., according to a large amount of True Datas, railway rockfall disaster is carried out to monitoring technique research.Conventional guard technology is realized by active protecting net system and passive protection net are installed.Active control technique is applicable to prospecting Dangerous Rock Body improvement that determine, large-scale; Passive Prevention Technique is applicable to the crag band, or the wire engineering is subject to the protection under the threat of rockfall disaster.Its advantage is effectively to protect falling rocks disaster threat object comprehensively, but is limited to the interdiction capability of passive protection system, is commonly used to tackle small-sized falling rocks.Effective setting of passive protection system depends on the degree of reliability of falling rocks motor behavior prediction, as motion path, jumping height, movement velocity, kinetic energy is isoparametric obtains.At present, active and passive Prevention Technique be Shortcomings all, once falling rocks is skipped or broken through the passive protection net, enters in the railway boundary and will normally run and produce great harm circuit.
Rockfall monitoring technique aspect along the railway, carried out research and the application of part both at home and abroad, the following problem of ubiquity: the one, part monitoring equipment somewhat expensive, can't widely apply; The 2nd, because the improper breakage caused of testing element installation method and the inaccurate phenomenon of data often occur, the 3rd, determining of forecasting model and warning trigger condition is more difficult; The 4th, endurance issues is more outstanding, and particularly testing element is subject to weather extremes to affect easy inefficacy.

(1) electric measuring method: adopt strain resistor, its precision is low, poor anti jamming capability, and the life-span is short, and on-the-spot the needs used power supply, and signal is difficult to long-distance transmissions, is not suitable for long term monitoring;
(2) GPS method: adopt global position system, its field apparatus needs maintenance, and scene needs power supply, special region can't be obtained signal, particularly can't record the STRESS VARIATION of geology inside, so can't be forecast landslide, as carry out multiple spot monitoring, this system cost costliness;
(3) image method: adopt the outdoor pick-up method, more directly perceived.But rain, mist and snow sky are difficult to identification, can not forecast, and scene needs power supply, and equipment is easily destroyed;
(4) fiber grating method: fiber-optic grating sensor has that volume is little, precision is high, the life-span is long, high reliability, with the advantage such as optical fiber compatibility, very easily is embedded to object under test inside, realizes the high precision of object, glitch-free Real-Time Monitoring.Can realize the digitizing sensing, but long-term stable operation under railway depopulated zone, non-Electric region and rugged environment especially.
Considering that southwestern railway is mainly in mountain area, is again foggy rainy few people area, the plant maintenance difficulty, and there is the hidden danger of damaging and stealing in general external device, therefore engineering adopts domestic state-of-the-art fiber grating sensing technology.
