It is as follows that the present invention solves the technical solution that above-mentioned technical problem is taken：
A kind of talus slide area high-speed railway resistant slide of the present invention deforms subgrade strengthening structure, it is characterized in that including：It reinforces
Body and support base, reinforcing body are set in the talus slide body below road structure, and support base is arranged at the top of reinforcing body；
Sliding layer and foundation of road bed, sliding layer are arranged on support base top surface, and foundation of road bed is arranged on sliding layer top surface, roadbed knot
Structure fills on foundation of road bed；Drag stake is arranged at intervals on the talus slide body of road structure uphill side along circuit extending direction
In, its underpart is anchored in good ground across sliding surface；Pulling force rope, both ends are fixedly connected with drag stake, foundation of road bed respectively.
The sliding layer is made of lower slider layer, the upper sliding layer respectively with support base, foundation of road bed fixation bonding, table
The smooth lower slider layer in face, upper sliding layer are made of the low frictional resistance composite geotextile material of high intensity.
Become the invention has the advantages that efficiently solving talus slide area road structure and not glided especially by its deformation
The problem of shape influences, structure construction is simple, good economy performance, has popularizing application prospect, and meet the requirement of environmental protection.

Component name and corresponding label are shown in figure：Reinforcing body 1, support base 2, sliding layer 3, lower slider layer 31,
Upper sliding layer 32, foundation of road bed 4, road structure 5, drag stake 6, pulling force rope 7, talus slide body A, good ground B, sliding surface C.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples：
Referring to Figures 1 and 2, a kind of talus slide area high-speed railway resistant slide deformation subgrade strengthening structure includes：Reinforcing body 1
With support base 2, reinforcing body 1 is set in the talus slide body A of 5 lower section of road structure, and support base 2 is fixed at reinforcing
1 top of body；Sliding layer 3 and foundation of road bed 4, sliding layer 3 are arranged on 2 top surface of support base, and foundation of road bed 4 is arranged in sliding layer
On 3 top surfaces, road structure 5 fills on foundation of road bed 4；Drag stake 6 is arranged at intervals on road structure 5 along circuit extending direction
In the talus slide body A of uphill side, its underpart is anchored in good ground B across sliding surface C；Pulling force rope 7, both ends respectively with drag
Stake 6, foundation of road bed 4 are fixedly connected.
Referring to Figure 1 and Figure 3, the sliding layer 3 with support base 2, foundation of road bed 4 by fixing cohesive lower slider layer respectively
31, upper sliding layer 32 forms, and the smooth lower slider layer 31 in surface, upper sliding layer 32 are by the low frictional resistance composite geotextile material of high intensity
It is made.
Referring to FIG. 1, FIG. 2 and FIG. 3, reinforcing body 1 is set in the talus slide body A of 5 lower section of road structure, solves talus and slides
Slopes vertical bearing capacity deficiency and Vertical Settlement problem.Reinforcing body 1 is solved using support base 2 and deforms problem of non-uniform, and is made
For the immobilizing foundation of lower slider layer 31；Using foundation of road bed 4 as the immobilizing foundation of upper sliding layer 32, and avoid top roadbed knot
Structure 5 is directly in direct contact the sliding effect for influencing sliding layer 3 with sliding layer 3.Using being pasted and fixed on support base 2 and road respectively
The small friction smooth interaction having between lower slider layer 31 and upper sliding layer 32 on base basis 5 so that talus slide, which glides, to be become
It can be easier to generate Relative sliding deformation when shape, between support base 2 and foundation of road bed 4.By pulling force rope 7 drag stake 6
It is fixedly connected with foundation of road bed 4, when deformation occurs to glide for talus slide, drag stake 6 can provide upward for foundation of road bed 4
Pulling force ensure that the road structure 5 on 4 top of foundation of road bed does not generate the deformation along glide direction.The structure allows slip mass
With deformation appropriate, but not the High Speed Railway Subgrade on top is influenced, structure construction is simple, good economy performance, has and pushes away
Wide application prospect, and meet the requirement of environmental protection.
Referring to Fig.1, for talus or containing the more talus slide body of stone, reinforcing body 1 preferably uses grouting and reinforcing body.Reference
Fig. 2 preferably uses cement fly ash gravel pile (CFG) reinforcing body for landslide o earth slope body.Reinforcement depth is right according to road structure 5
Sedimentation and the requirement of bearing capacity, which calculate, to be determined.
Referring to Figures 1 and 2, the support base 2, foundation of road bed 4 are poured using armored concrete, and thickness is not less than
0.3m.The drag stake 6 is consistent with the elevation of foundation of road bed 4 using reinforced concrete pile, installation position and elevation.The drawing
Power rope 7 is made of high strength steel strand, and both ends are fixedly connected with drag stake 6,4 tensioning of foundation of road bed.The reinforcing body 1, branch
The width that setting width L of the pedestal 2 on the upside of the body A of talus slide is more than foundation of road bed 4 is supportted, setting width L is more than 1.0m.
The above is a kind of talus slide area high-speed railway resistant slide deformation subgrade strengthening of the present invention that explains through diagrams
Some principles of structure are not intended to the present invention being confined in the shown and described concrete structure scope of application, therefore every institute
It is possible that the corresponding modification being utilized and equivalent, belong to the apllied the scope of the claims of the present invention.
