Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
See Fig. 1, Fig. 2 and Fig. 3, this anchored slope distortion intelligent monitor system is mainly divided into three parts: Part I, the measurement of data, the height of the underground water table of slope soil is measured in the pressure change that the instrument of DATA REASONING comprises the slippage that the test of the displacement of each measuring point of side slope surface tested by Fiber Bragg Grating FBG displacement transducer 6, slope soil measured by tiltmeter 4, dynamometer 8 measures original anchor pole 9 or anchor cable end, osmometer 5, soil pressure cell 10 measures side slope toe place soil pressure; Part II, the collection of data.Utilize Wireless data acquisition unit 14 to collect the data measured, import the data of collection into terminal 13; Part III, the judgement of data computational analysis and slope stability, imports the data of collection into judgement that computing machine carries out computational analysis and relevant slope stability.
This method can carry out intellectual monitoring to anchored slope distortion by comparison system.
See Fig. 1, Fig. 2 and Fig. 3, displacement monitor is made up of sensor, wire rope 11 and block 3, sensor comprises Fiber Bragg Grating FBG displacement transducer 6, semi-girder 7, constant temperature oven 1 and spring 12, every grade of side slope surface carries out every 2m the block 3 arranging displacement monitor to toe from top, slope, the soil body of displacement monitor point utilize weight compacting and the soil body place casting concrete pushed up on the slope of compacting as the bearing of displacement monitor, prevent during monitoring because other factors such as rain drop erosion make the monitoring of displacement monitor occur deviation.Block 3 wire rope 11 is connected with the spring 12 of displacement monitor, a fixed pulley 2 is being fixed through corner, Slope top, displacement monitor is laid in the place of Slope top, one of spring 12 in displacement monitor is connected with wire rope 11 other end connecting cantilever beam 7, semi-girder 7 concreting is fixed on the top, slope of side slope, the change of outer cover constant temperature oven 1 control temperature, and the Fiber Bragg Grating FBG displacement transducer 6 (being called for short FBG) of displacement monitor is tightly fixed on the centre position of semi-girder 7, when the soil body of side slope occurs to slide, drive the movement of block 3, thus cause the bending of semi-girder 7 and change the wavelength of Fiber Bragg Grating FBG displacement transducer 6.Thus the sedimentation of slope soil can be calculated.Fixing a fixed pulley 2 through Slope top in the corner on Slope top, guaranteeing Fiber Bragg Grating FBG displacement transducer 6 energy accurate recording block 3 displacement on semi-girder 7, thus the sedimentation deformation of the soil body can be drawn.Equicohesive material selected by semi-girder 7, can produce certain flexural deformation when masterpiece is used for cantilever end outside.Fiber Bragg Grating FBG displacement transducer 6 is tightly attached on semi-girder 7, and can have identical flexural deformation under external force with semi-girder 7.Block 3 inserts more than slope soil 10cm, and guarantees not slide because of rainwash in its position in the location point concreting of inserting.
The cloth of tiltmeter 4 sets up an office and is arranged on Slope top edge, holes to the monitoring point on Slope top, and the degree of depth of boring should reach side slope toe same level position.Insert tiltmeter 4, the gap mortar existed in tiltmeter 4 and side slope are holed is built, guarantee that reducing tiltmeter collects the error of data, the part exposing domatic tiltmeter 4 is carried out anchoring and guarantee to produce loosening, and record the angle of the deflection of now tiltmeter 4.
Dynamometer 8 is replaced supporting plate place, the end soil body at original prestress support anchor rod 9 or anchor cable, and guarantee that dynamometer 8 is tightly close to the supporting plate of slope soil and anchor pole 9 or anchor cable, utilize rope by together with dynamometer and anchor pole or anchor cable tightly colligation, guarantee that dynamometer 8 does not come off at test period.And the number of degrees of record dynamometer 8 now.When slope soil start to occur sedimentation move time, the axle power of anchor pole 9 or anchor cable changes and changes the reading of dynamometer 8, the reading of moment record dynamometer 8 during monitoring.
The method utilizing clear water to hole at Slope top place vertically pierces the height that the degree of depth is 1/3rd of this grade of side slope, in construction, under boring limit, limit, aperture is the pipe box of osmometer size, terminate after creeping into projected depth, after determining that elevation is errorless, add medium coarse sand with thin copper mesh, osmometer 5 being put into aperture is wrap up medium coarse sand in the thin copper wire net of about 1mm, descends design altitude in hand-hole exactly.After osmometer 5 is buried underground, stop waiting 24h, after there is no larger depression; for protecting the cable stayed outside hole, carrying out burying protection underground with the orifice tube that 2 cun of pvc pipes are 70 ~ 100cm long, finally having carried out pulling out sleeve pipe; adopt the way of tip-tap, prevent osmometer 5 to shake bad.
At side slope toe place 10cm depth, fixing soil pressure cell 10, by the compression face of soil pressure cell 10 towards slope soil, fills at soil pressure cell periphery fine sand, involves the wire of soil pressure cell 10.
See Fig. 1, Fig. 2 and Fig. 3, the Fiber Bragg Grating FBG displacement transducer 6 of Fiber Bragg Grating FBG displacement monitor, dynamometer 8, tiltmeter 4, osmometer 5 and soil pressure cell 10 are communicated to connect by Wireless data acquisition unit 14 and terminal 13.Wireless data acquisition unit 14 is utilized to collect the data such as the dynamometer 8 of axle power and the osmometer 5 of slope soil of the vertical displacement of the FBG6 on Slope top, tiltmeter 4, anchor pole 9 or anchor cable, and the data of collection are transferred to terminal 13, terminal 13 is utilized to carry out data analysis, whether analysis of slope is in steady state (SS), if side slope is in steady state (SS), system prompt side slope is in steady state (SS), otherwise then prompts for side slope and be in instability status.
