This analysis is based on relevant engineering cases in domestic and international contexts, the structural system of assembled bridge piers is introduced. The advantages and disadvantages of different types of assembled piers are analyzed and compared from the perspectives of structural stress performance, durability and construction convenience. Through analysis of the existing research results found that: most of the existing research focused on the seismic performance of the piers, but the research involving the compressive and shear performance of assembled RC piers is still relatively rare, Pacifications for Design of Highway Precast Concrete Bridges (JTG/T 3365-05—2022) although the structural calculation method of assembled concrete piers, but not yet according to the different types of assembled piers of the splicing structure characteristics, the corresponding limit of the local structure bearing capacity calculation method; Pacifications for Design of Highway Precast Concrete Bridges (JTG/T 3365-05—2022), Specifications for Construction of High Wary Precast Concrete Bridges (JTG/T 3654—2022) for some types of assembled piers construction requirements, construction techniques, some local standards have involved assembled piers seismic design, construction, acceptance, etc. These standards can be used to guide the design and construction of some types of assembled piers, but its content is still not comprehensive. On this basis, the shortcomings of assembled piers in structural design, construction, quality control and other aspects as well as the future development direction are proposed.
