(2) Solve the problem of damage to the concrete structure of bridges and culverts in the severe cold areas and frozen soil areas in the north (frost heave and thaw settlement).
(3) It is conducive to improving the "dislocation" phenomenon at the junction of soft soil foundation structure and embankment, improving the comfort and safety of driving, and reducing the cost of post-construction operation and maintenance.
(4)It has high rigidity and high strength, reasonable structural stress, uniform load distribution, and certain anti-deformation ability. Structurally, it has the property of transversely compensating for displacement.
