Description
Technical field
The present invention relates to a kind of supervisory system, particularly a kind of seismic survey supervisory system that detects underground water table.
Background technology
China is located in Eurasian plate edge, is positioned at the area, boundary of Pacific-oceanic plate, Indian Ocean plate and Eurasian plate, and plate movement is relatively active, and earthquake occurs frequent, so China is one of country that seismic activity level is the highest in the world, earthquake disaster is the heaviest.
To compatriots impress deep Wenchuan earthquake, Yushu earthquake, Yaan earthquake, these violent earthquakes had caused very big destruction to Chinese economic construction and social development, also to the people's lives and property, caused very large threat in recent years.Therefore carry out every protection against and mitigation of earthquake disasters work, scientifically prediction and the disaster that strick precaution earthquake brings, is the instant difficult problem that need to solve of China.
Underground water table refers to the elevation of the water surface in underground reservoir.Water level is dynamically observed, and refers to the time dependent process of ground water level.The result of measuring, the often variation with water level numerical value in time series represents, the base unit of water level numerical value is m.Before real-time monitored shake, the dynamic change of underground water table, has very important realistic meaning and actual value.
Earthquake is the result that in the earth's crust, rock stress constantly accumulates, and underground water is as one of most active ingredient in the earth's crust, there is ubiquity, mobility and difficult constrictive feature, so the variation of underground water table can be recorded the variation of rock stress delicately, therefore utilize science means monitoring underground water table variation its earthquake prediction is had to reference value very much.The variation of water level is a very important index of omen before shake.Through the development of these several years science and technology, China has built up by the observational network that in the Dynamic Acquisition earthquake preparation of observation underground water, generation, disaster process, geophysical field changes.Observation practice shows, the effect of breeding and occur to be unable to do without fluid of earthquake, and historical summary shows, in China relatively successfully forecasts earthquake in recent years several times, water table measure has all been brought into play vital role.
Groundwater shake is very sensitive, illustrate that underground fluid has very strong information transfer capacity, but because distributing, underground water reaches underground 20 ~ 30 kms, and the ANOMALOUS VARIATIONS of ground water level can be accompanied by rapidly earthquake on the horizon, the even sometimes monitoring of first tens seconds ability before shake draws, and the collection point of adding underground water table also will very strictly be chosen and just can make it not affected by the factor beyond earthquake.The Monitoring on Dynamic Change of underground water table and analysis are difficult point and the focus of countries in the world scientific research always.
The seismic groundwater position of China monitoring in recent years starts to obtain the attention of national correlation department, passed through the stage that establishment, reform, development, state-of-the-art technology upgrade, built up the front water table measure net of a very huge shake, before these water levels are seen SCM Based shake, water table measure system survey grid has played great function to the prediction of earthquake and analysis, and on protection against and mitigation of earthquake disasters, work has produced positive impact.But, the present situation of the layout of observational network, the facility of inspection well, monitoring station construction and observation technology, or the effect of its monitoring and prediction, have to be adjusted, optimize, transformation, improve and innovate.Aspect observation technology, to make good use of modern science and technology especially, measure in real time, exactly the ANOMALOUS VARIATIONS of water level before shaking.
The means of the existing water table measure of China and instrument have following several:
1, underground water table is surveyed cup
Underground water table is surveyed cup and is actually a metal hollow cylinder that is about 10 cm, an end opening, and other end sealing, one of blind end is lining rope.During measurement, stand in aboveground people and carrying lining rope, openend is downward, surveying cup, put to well water face, pull the upper and lower handling cylinder of rope.When the cylinder opening end touching water surface, can sound, can determine thus cylinder survey cup and arrive the water surface, then read lining rope high scale, just obtain groundwater level depth value.This method measuring error is larger, and can only measure water surface buried depth, can not measure height of water level, and institute is in this way no longer applicable.
2, electrically contact suspended type water gauge
Have another name called " suspended type water-level gauge ", " Water level measuring rule ".Water gauge is comprised of water level suspending hammer, survey chi, contact water surface indicator, survey chi folding and unfolding disk etc.Surveying chi is a kind of metal tape of softness, is connected to 2 wires above, and tape measure is marked with scale accurately.Water level suspending hammer has constant weight, and there is the hard contact of 2 mutually insulateds its end, and contact is connected with wire.During use, artificial folding and unfolding suspension cable, puts into suspending hammer under water, when 2 contact contact underground water, and resistance decreasing (conducting).
The loudspeaker that are now connected with 2 wires on the indicator on ground, pilot lamp, pointer etc. send signal, represent to have arrived groundwater level.From surveying chi, read reading, can know groundwater level depth.This water-level gauge descends height of water level equally immeasurably.
3, float-type underground level gauge
Float type level meter, utilizes float to follow the tracks of fluctuation in stage, mechanically direct-drive record.With float gauge, need there is logging equipment.Being float and being furnished with suspension cable, water level wheel, balance bob etc. of induction SEA LEVEL VARIATION.The sensitivity that float sensed water level changes is poor.Bury of groundwater is larger, and suspension cable is long, also affects water level induction sensitivity.
4, pressure type underground level gauge
The principle of pressure type underground level gauge is to export corresponding height of water level signal according to measuring hydraulic pressure.Apparatus measures goes out after the hydrostatic force of following certain point of surface level, then converts and obtain the height of the above water level of this measurement point according to the density of water body and acceleration of gravity.On the water surface, bearing atmospheric pressure, so the pressure that measuring point measures to be measurement point above water pressure that water colunm height forms and the atmospheric pressure sum of water surface under water.The point that is specifically designed to the front water level acquisition of shake buries very deeply, and its hydraulic pressure can not be subject to atmospheric impact.Sensor connects with private cable, and itself is with the function of signal amplification and temperature compensation.Generalized case lower pressure sensor is suspended on below the lowest water level in underground water well logging with special-purpose cable, and measure and control device on the ground.The level measuring accuracy of pressure type underground level gauge is higher than float-type underground level gauge.
5, ultrasonic type water-level gauge
Ultrasonic type water-level gauge utilizes the principle of acoustic reflection to measure water level.By propagation medium, be divided into water Jie formula and aerosphere type.
Sound wave is propagated with constant speed in same medium, and when running into the dielectric interface of different densities, sound wave reflects.Water Jie formula is that generator is arranged on to the bottom, vertically to water surface transmitting ultrasound wave; Aerosphere type is that generator is fixed on to a certain eminence in air, to water surface transmitting ultrasound wave.Water Jie formula velocity of sound is affected by floating outstanding particle concentration in water temperature, hydraulic pressure and water, in measuring process, will proofread and correct sound wave.Aerosphere type will be proofreaied and correct temperature impact, and its advantage is not affected by pasture and water, silt etc. in water, and shortcoming is the impact that is easily subject to stormy waves, and especially current are anxious, and the place that surge is large, should not install ultrasonic water level gauge.
Earthquake is that rock stress in earth movement constantly strengthens, and has surpassed rock mass and has born maximum intensity and the result of the generation seismic event that breaks.In a large amount of observation and analysis research, show, the sensitive rock stress that records of underground water potential energy changes, and it is very significant utilizing Anomalies of Groundwater Level to change to carry out earthquake precursors forecast.China's seismic groundwater position precursor data collection is at present lower with management level, and partial data needs in artificial input computing machine.While there is mistake, also need manually to go to investigate one by one, waste time and energy.
