Description
Technical field
The utility model relates to railway construction field, specially a kind of high-speed rail fragment-free track slab structure.
Background technique
Non-fragment orbit replaces ballast track bed come when transmitting driving using the preferable concrete of self stability or asphalt cemented ballast bed
Dynamic and static load, and the flexible deformation that needs of while driving a vehicle is mainly by being arranged in the unit material of explication under rail or fastener
It provides.Ballastless track structure design requirement its with enough antifreeze safeties, especially to its underpart structure lay a railway track complete
The subsequent sedimentation deformation requirements occurred afterwards are very stringent.So the long-time stability of non-fragment orbit route are preferable, especially in height
Under fast driving condition, belong to a kind of upper structure type seldom to need repairing under normal circumstances.
According to the type of substructure, non-fragment orbit can be divided into non-fragment orbit on roadbed, in tunnel on non-fragment orbit and bridge
Non-fragment orbit three categories.Simultaneously according to different parameters, non-fragment orbit can be divided into different structure types, quovis modo
On the one hand ballastless track structure makes the load of system due to using the biggish hardened material that coheres of rigidity as road bed board
Transmitting, diffusion function significantly improve, and on the other hand its ability for adapting to substructure sedimentation and deformation but greatly declines, so various
Requirement of the ballastless track structure to basic roadbed in other words is essentially the same.A large amount of on-the-spot test comparison shows at it
In the identical situation of his condition, when driving, the dynamic load difference under non-fragment orbit and Ballast track in bedding and roadbed is very big, such as
Dynamic stress and vibration velocity, in comparison, the difference of dynamic load is smaller in roadbed under the conditions of different ballastless track structures.From this
Two o'clock is set out, and is conceived to the design of ballastless track roadbed, this chapter is typically with German sleeper flush type non-fragment orbit Rheda system
