Mechanics property and adaptability of approach slab;

With the typical geological condition and road filling in Ningbo, the causes for bump at bridge head are analyzed and proposals recommended, using CMC jointly with the approach slab to solve the problem by reducing differential settlement at the abutment.

In this paper, finite element method is employed to analyze the mechanical behaviors of approach slabs between bridge abutment and pavements subject to axle loadings.

In this paper with introduction on the design method of abutment back in China and abroad and based upon the united design principle of bridges, culverts and abutment back the butt strap method is introduced from slope gradient, length, thickness, reinforcement and other aspects.

The conduct wire connecting the negative terminal of battery and the metal part of the automobile body is called bond strap.
