The bridge is generally a structure which is erected on rivers, lakes and seas and allows vehicles, pedestrians and the like to smoothly pass through. In order to adapt to the modern high-speed developed traffic industry, bridges are also extended to be constructed to span mountain stream, unfavorable geology or meet other traffic needs, so that the buildings are convenient to pass. The bridge generally comprises an upper structure, a lower structure, a support and an auxiliary structure, wherein the upper structure is also called a bridge span structure and is a main structure for spanning obstacles; the lower structure comprises a bridge abutment, a bridge pier and a foundation; the support is a force transmission device arranged at the supporting positions of the bridge span structure and the bridge pier or the bridge abutment; the auxiliary structures refer to bridge end butt straps, tapered revetments, diversion works and the like.

When a bridge is built, piers are often required to be placed at specified positions for building, the piers are sub-buildings which support a bridge span structure and transfer constant loads and vehicle live loads to a foundation, and bridge abutments are arranged in two lakes of the bridge. The bridge pier is arranged between the two bridge abutments. The pier is used for supporting a bridge span structure: the abutment supports the bridge span structure and is connected with the embankment to prevent the embankment from sliding. In order to protect the separation platform and the embankment filler, protection and flow guide projects are usually performed on two sides of the separation platform.

The pier mainly comprises a top cap and a pier body. The abutment mainly comprises a top cap and an abutment body. The top cap is used for dispersing and uniformly transmitting the large and concentrated force transmitted from the bridge span support to the pier body and the platform body. Therefore, the top cap is constructed by adopting materials with higher strength, generally reinforced concrete with the thickness not less than 40 cm and not less than 200 grades. In addition, the top cap also needs to have larger plane size, so that a necessary working surface is provided for construction beam erecting and maintenance. The pier body and the platform body are main structures for supporting the bridge span, not only bear all loads transmitted by the bridge span structure, but also directly bear various loads such as soil pressure, water flow impact force, ice pressure, ship impact force and the like, so that the pier body and the platform body have enough strength, rigidity and stability.
