Abstract
The invention discloses Earthworking reinforced bars to the reinforcement means of open-pit mine blast side slope, and model reinforcement arrangement is the equal mode for cloth cloth muscle in open-pit mine blast side slope using 4 layers, every layer 5 rib tape of from top to bottom 4545 arrangements；The joint length of rib tape is respectively 10m~50m, it is ensured that while all rib tape all pass through potential sliding surface, increase rib tape width appropriate.The beneficial effects of the invention are as follows taking Earthworking reinforced bar mode to carry out refuse dump slope reinforcement in engineering there is preferable applicability, certain booster action can also be played to the sliding resistance of potential water use while increasing the frictional behaviour that refuse dump is banketed.By reinforcement, slope stability be improved significantly.
Description
Technical field
The invention belongs to brick or concrete duct fields, are related to Earthworking reinforced bar to the reinforcement means of open-pit mine blast side slope.
Background technique
In all kinds of engineering constructions, reinforced earth bulkhead by metope, bankets with muscle material etc. as a kind of novel soil-baffling structure
Composition, with its occupied area, few, adaptable, cheap, easy construction, anti-seismic performance are good is not only increasingly being applied to
City builds, railway, highway, at the same be applied to landslide prevention and treatment, land control, dam construction, riverbed regulation, port engineering,
Water and soil conservation etc..But the permission soil body big for open-pit mine blast earth volume has the characteristics of deformation to a certain degree, it was initially believed that native
Work reinforcement has preferable applicability to the reinforcing of refuse dump side slope.At the same time, the length of muscle material, arrangement spacing and rigidity pair
Reinforced earth bulkhead deformation has a great impact, thus the reinforcement means and same that reinforced earth bulkhead uses under different operating conditions
Reinforcing parameter used by method is also not quite similar.
Summary of the invention
The purpose of the present invention is to provide Earthworking reinforced bars to the reinforcement means of open-pit mine blast side slope, and of the invention is beneficial
Effect is to take Earthworking reinforced bar mode to carry out refuse dump slope reinforcement in engineering to have preferable applicability, is increasing refuse dump
Certain booster action can also be played while the frictional behaviour banketed to the sliding resistance of potential water use.Pass through reinforcement, side
Slope stability be improved significantly.
The technical scheme adopted by the invention is that model reinforcement arrangement is to use in open-pit mine blast side slope from upper
To the equal mode for cloth cloth muscle of 4 layers, every layer 5 rib tape of lower 4545 arrangement；The joint length of rib tape is respectively 10m~50m, it is ensured that
While all rib tape all pass through potential sliding surface, increase rib tape width appropriate.
Further, every layer away from 1m~5m, and side slopes at different levels are respectively arranged.
Further, side slope middle reinforcement length longest.
Specific embodiment
The present invention is described in detail With reference to embodiment.
Model reinforcement arrangement: in open-pit mine blast side slope using 4 layers, every layer of 5 rib tape of from top to bottom 4545 arrangements
Equal mode for cloth cloth muscle.Model test the result shows that, horizontal mode cloth muscle is relatively reasonable.According to model test as a result, determining existing
Reinforcement arrangement, each layer rib tape spacing by model test result and side slope actual conditions be away from 1m~5m with layer it is best, respectively
Grade side slope is respectively arranged.
How arranging can be achieved the purpose that control the deformation failure that bankets with lesser reinforcement amount, from top to bottom four layers of rib tape
Joint length be respectively 10m~50m.It is calculated based on limiting equilibrium method, it is ensured that all rib tape all pass through potential cunning
While face, increase rib tape width appropriate, the joint length of reinforcement can change most preferably within the scope of 10m~50m, side slope middle
Reinforcement length can be lengthened suitably, be set as longest.
The present invention explores being applicable in for reinforced earth bulkhead by refuse dump slope table development of deformation law study and simulation test
Property, and then according to field condition, working characteristics and consolidation effect of the comparative analysis reinforced earth bulkhead under the conditions of Different Effects obtain
To draw a conclusion:
The development of deformation that slope epitope is moved shows apparent stage, and periodic precipitation and accidental earthquake are to need to consider
Stability factor.Side slope is substantially at state of limit equilibrium under drainage condition, and there are local slumps and two kinds of overall collapse
Possible failure mode.Appropriate reinforcement is significantly improved to the stability of drainage condition, full water bar part, seismic condition slope
Effect.First order side slope is the emphasis of preventing land slide, and encryption cloth muscle appropriate can effectively reduce intense rainfall condition slope part
The danger of slump and overall collapse, and the wedge action of geotechnological rib tape can greatly improve the anti-of slopes compared with calculated result
Shock stability.The frictional behaviour of refuse dump miscellaneous fill and close can be increased by taking reinforced earth bulkhead scheme to carry out refuse dump slope reinforcement
Solidity, slopes regional area and overall stability under the conditions of different degrees of raising Different Effects.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
