Description
Technical field
The utility model is related to monitoring technology for geological hazards field, especially a kind of landslide multi-point displacement intellectual monitoring dress
It puts.
Background technology
Landslide is the sliding geological phenomenon that slope Rock And Soil is occurred along logical shear breakage is used to.The mechanism on landslide is
Caused by shear stress has been more than the shearing strength in the face on a certain slide surface.Industrial and agricultural production and people's life wealth are usually given in landslide
Production brings about great losses, the even destructive disaster of some.
Landslide harm most important to rural area is to destroy farmland, room, injury people and animals, deforestation, road and agricultural
Mechanical facility and water conservancy and hydropower facility etc. even cause crushing disaster to rural area sometimes.It usually pounds and buries positioned at the landslide in cities and towns
House destroys factory, school, institutional settings etc., and damages various facilities, causes to have a power failure, cuts off the water, stops work, and even destroys sometimes
Entire cities and towns.The landslide of industrial and mining area is happened at, mine facility can be destroyed, injures and deaths worker damages workshop, makes mine stop work and production,
Often result in heavy losses.
Landslide is had by sliding speed division：Creep landslide, usual people can only pass through with being visually difficult to see its movement
Instrument observation could be found；It comes down at a slow speed, slides several centimeters daily to several tens cm, people can observe directly landslide with naked eyes
Activity；Middling speed comes down, and slides the landslide of several tens cm to several meters per hour；HIGH-SPEED LANDSLIDE, it is per second to slide several meters to tens of rice
Landslide.
Except wriggling comes down, people can have found to come down and withdraw early danger zone early.It comes down for wriggling,
Its concealment is stronger, and harmfulness is bigger, and people are difficult to find, even if being unable to estimate it since its slip is slower after finding
Liveness brings difficulty to people's disaster prevention and danger avoidance.China is the multiple area of geological disaster, and all parts of the country landslide is ten hundreds of, generally
Belong to wriggling landslide, the safety of life and property of serious threat this people group.
The existing geological disaster landslide monitoring method in China has mass presdiction and disaster prevention and professional monitoring two ways at present.
Mass presdiction and disaster prevention monitoring mode generally has artificial monitoring stake and landslide pantograph, and wherein personal monitoring's stake is in slip mass
The staking out of two edge-on two, crack, by the relative displacement of two monitoring stakes of tape measure, and makes a record, for observing crack
Tension degree；Landslide pantograph is a kind of follow-on personal monitoring's stake, and tape measure and electronic component are integrated together, and increased
Warning device is added, equipment one end is mounted on slip mass crack and stablizes one side, and drawstring one end unstable one side of fixing crack is sliding
Slope pantograph inbuilt displacement threshold switch, after displacement reaches early warning value, landslide pantograph triggers external alarm equipment alarm, reminds
Resident prevents and reduces natural disasters.
Professional monitoring mode has drawstring displacement monitor, earth's surface GNSS monitors, deep soils instrument, ground laser thunder
It is monitored up to scanner and InSAR.Its medium pulling rope displacement monitor is installed to slip mass crack both sides, monitors the opposite of crack both sides
Displacement, and monitoring data are transferred to distant early warning center by GPRS network, realize field unattended automatic collection work(
Energy.Its precision reaches 1mm grades, and systematic comparison is stablized；Earth's surface GNSS monitors are using satellite positioning and algorithm realization slip mass
The absolute displacement monitoring of table (X, Y, Z) three-dimensional, precision reach 5mm grades, whole to hold slip mass variation tendency for simulation modeling
There is absolute predominance；Deep soils instrument is to calculate landslide using the inclination angle in borehole inclinometer measurement drilling at slip band
Relative shift, it is with obvious effects for wriggling landslide monitoring；It is sharp that ground laser radar scanner is that profit is computerizedd control
Optical radar quickly scans slip mass entire surface, and scanning result and history scan data are compared, and calculates slip mass
Deformation tendency；InSAR monitorings are to obtain slip mass influence figure using spaceborne or airborne Interference radar, wherein each pixel both included
The radar raster-displaying strength information of ground resolution element also comprising the phase information related with oblique distance, will cover areal
The phase value of two width radar image respective pixels subtracts each other an available phase difference figure, these phase signals can reflect place's earth's surface
Deformation extent.
Utility model people has found that there are following defect and deficiencies for the prior art in the process of implementing the utility model：
1st, drawstring displacement monitor cannot monitor the variation tendency of entire slip mass, if it is desired to monitoring entire slip mass variation
Trend is caused great in constructing amount and of high cost, it is necessary to lay multiple devices；
2nd, earth's surface GNSS monitors power consumption is larger, and cost is higher, and computing speed is slow, and is affected by electromagnetism and environment,
Seriously affect precision；
3rd, deep soils instrument does not possess drilling since it is in drilling for overwhelming majority landslide,
Installation deep soils instrument needs are drilled, and workload and cost increase much；
4th, ground laser radar scanner is the drawback is that vegetation cannot be filtered out, for the southeast and the southwest ground of dense vegetation
Area, monitoring effect are bad.
