After journey completion, different sedimentation changes will occur in vehicle operation, Embankment Subsidence amount is larger, and abutment settling amount is smaller, if
The excessive track generation vertical variations that will cause vehicle wheel in road traveling of sedimentation difference cause vehicle bound to produce " jump
Car " phenomenon, and car speed car phenomenon of jumping higher is more serious, and under vehicle dynamic load continually multidirectional impact, with sedimentation
The further increase of amount, vehicle dynamic load coefficient is incrementally increased, and vehicle dynamic load impulsive force is also further strengthened, and accelerates road surface
Sedimentation and road surface breakage.Its main cause mainly has：1st, engineering technology requirement is different, 2, the physical property of different material it is different,
3rd, Mechanical Form is different when abutment is with embankment bearing load.
Highway bridge basis basis《Highway bridge and culvert ground and foundation design code》（JDG D63-2007）4.3.3 it is " adjacent
Differential settlement difference between pier（The sedimentation in construction is not included）Bridge floor should not be made to form the additional longitudinal slope more than 2 ‰（Tear open
Angle）" regulation, the sedimentation difference of point to point should be kept within the scope of specification permission.Assuming that at abutment and embankment edge A points
The settling amount As=0 on road surface, the embankment B point settling amount Bs=2cm at abutment and embankment edge 1m, then form after its sedimentation change
Additional longitudinal slope α=2/100=2%（Such as Fig. 2）, that is to say, that its sedimentation difference DELTA s is 10 times of specification permissible value;If abutment
The sedimentation difference DELTA s ＞ 2cm of A points and B points, even if to take measures on customs clearance extend to 10m by the distance of settlement point B and A points, its
The additional longitudinal slope α formed after sedimentation change is still above 2 ‰, it is clear that do not meet specification regulation.But, in reality, such case
It is relatively conventional.Especially the sedimentation difference of embankment high, Roadbed on soft ground, soft base embankment high and abutment is generally much larger than 2cm,
Therefore it is easier jump car phenomenon occur.
In order to will not highway pavement form " knuckle " or make knuckle in the range of code requirement, generally designing and constructing
When take abutment and embankment joining section the measure such as ground and embankment consolidation process, hazard to bridge's pier reduction embankment and abutment linkage section
Interior Embankment Subsidence amount, reduces embankment with the sedimentation difference of abutment to meet regulation of the specification to additional longitudinal slope；But, due to road
The influence of the factor such as the otherness of the material conditions and physical and mechanical property of dike and ground and the complexity of execution conditions, is adopted
The corresponding measure for taking often is difficult to achieve the goal, and the road of highway, bridge junction are still present end of the bridge " jump car " phenomenon, influence row
Car safety and the comfortableness for multiplying, driving personnel.

It is current to change it is an object of the invention to provide a kind of highway embankment and the anti-jump car device of abutment joining section Fuliang
" jump car " present situation that highway bridge junction surface position is present, meets《Highway bridge and culvert ground and foundation design code》（JDG D63-
2007）4.3.3 " differential settlement difference between adjacent pier（The sedimentation in construction is not included）Bridge floor should not be made to be formed more than 2 ‰
Additional longitudinal slope（Tear angle open）" regulation requirement, propose bridge, road joint " two settlement point distance controllings " conception, by shadow in embankment
The settlement point that sound meets above-mentioned code requirement is designed with reference to the settlement request of Bridge Pier.
It is of the invention to be contemplated that：1 section is set in highway embankment and abutment joining section（Across）" beam ", and using abutment end phase
Fixation, embankment end and beam body are declined on base course with respect to free floating with the sedimentation of embankment, therefore this beam is called " floating
Beam ", makes road surface curve to form larger " tearing angle open ", realizes that vehicle drives towards embankment from bridge floor relative stiffness objects upstream relatively soft
Property the transition sailed of objects upstream, improve the balance of vehicle operation, so as to reduce vehicle dynamic load coefficient, vehicle is mitigated or eliminated
Because jumping the impact of car road pavement；Even if as the extension of highway operating time, the settling amount further increase（More than 4cm）,
The additional longitudinal slope more than 2 ‰ is formed at abutment A points and Fuliang B points（Knuckle）, it is also easy to be adjusted by Local Road Surface regulation, allow
The change of additional longitudinal slope substantially within the scope of code requirement or is more or less the same in longer time, reaches improvement driving condition
Purpose, meet highway communication to road speed higher develop the need for.
