1.2m, section of jurisdiction thickness are 0.3m, and piecemeal number is 6 pieces, and section of jurisdiction concrete is C50.The geological condition of the Tunnel Passing from up to
It is respectively artificial earth fill, silt and silty clay, silty sand clay down；Tunnel is located in farinose argillic horizon, buried depth 10m ~ 30m；
Underground water is 1 ~ 3m of subsurface.By taking the section of buried depth 12m as an example, stress is as shown in Figure 3a（Wherein data unit is kNm）.
Under least favorable load action, section institute bending moment such as Fig. 3 b（Wherein data unit is kNm）, section of jurisdiction inside top and
It is pressurized on the inside of tension on the outside of side, section of jurisdiction top outer and side, moment of flexure maximum value is respectively 125.5 kNm and 80 kN
M according to concrete material characteristic, should lay strain gauge 11 in position as shown in Fig. 3 c on the outside of the section of jurisdiction inside top and side,
When monitor value is more than 58με（The crack stress of corresponding concrete）When, it should pay close attention to, when monitor value is more than 800μεWhen, Ying Jin
Enter the state of alert.
The inspection that the position setting of inspection point is then provided according to terminal is planned to complete, in general, inspection point position
By tunnel component（Tunnel duct piece, vertical shaft, unicom road, guarded drainage facility etc.）It lays respectively, it should be long by component when being laid per component
Degree or area are evenly dividing, and for the more serious disease occurred during inspection, inspection point should be added at this, strengthens inspection
It looks into.The vertical range of the laying height distance pavement of road of inspection point should be less than 2m.The electronic cyclic instrument has corresponding inspection
Software can be acquired and store to inspection data, and with wired or wireless data-transformation facility.
The polling period of tunnel inspection work is preferably calculated by following equation,
Wherein N represents the design life of structure,nRepresent the service time of structure, D represents the inspection week of inspection work
Phase.By the formula it is found that structure polling period meets curvilinear motion relationship shown in Fig. 4 with the service time（It is with N=100 year
Example）.Tunnel structure is at the initial stage of building up it can be seen from the curve（0 ~ 20 year）Polling period is preferably 40 days ~ 37 days, runs mid-term
（21 years ~ 60 years）Polling period be preferably 37 days ~ 32 days, run the later stage（61 years ~ 100 years）Preferably 32 days ~ 7 days.
The workflow of tunnel structure electronization cruising inspection system is as follows.
First, inspection work planning is completed on computer terminals, that is, determines action, the inspection of each secondary patrol task
Position and corresponding patrol officer are put, then inspection open space planning is sent to each electronic cyclic instrument by data management terminal, is patrolled
Inspection personnel hold electronic cyclic instrument and carry out data acquisition to scene；Position in being planned by inspection be laid with electronic tag,
Sensor and the data acquisition locating module with sensor cooperation, each electronic tag and data acquisition locating module and phase
The inspection point answered is corresponding, and patrol officer is according to inspection programme path in electronic cyclic instrument, successively by each in ordered pair tunnel structure
Inspection point carries out inspection, and at each inspection point, electronic tag is scanned, and information is fed back to by electronic tag scanner
Electronic cyclic instrument, electronic cyclic instrument call the scope of examination required by the inspection point, by inspection according to the information in electronic tag
Personnel are checked and are judged, and personnel to be inspected are completed after checking information at this, and corresponding inspection result is write by scanner
Enter to electronic tag and stored, when being laid with sensor at inspection point, patrol officer adopts the data mating with sensor
The data of collection module are wirelessly collected in electronic cyclic instrument, and live inspection information is written built in data acquisition module
Electronic tag, complete the inspection work at the inspection point, the safe class of the inspection point determined according to the monitoring parameters.
In electronic cyclic instrument, by the monitoring parameters of sensor（The strain value of such as key sections, section of jurisdiction faulting of slab ends value, soil pressure force value）By three
Grade is divided, respectively safe condition（In the range of the safety value of parameter）, pay close attention to state（Safety value ~ ginseng of parameter
The 40% of number limiting value）And the state of alert（The 60% of 40% ~ parameter limits of parameter limits）, when being judged as paying close attention to
During state, the polling period at the inspection point is preferably foreshortened into original 1/3rd, monitoring；When be judged as warning shape
During state, inspection should be carried out daily, and report relevant departments, find out disease causes in time and repair.
