In　order　to　adapt　to　the　development　of　the　railway　bridge　engineering　in　severe　/　alpine　regions　and　off⁃　shore　regions　with　short　construction　period，and　to　improve　the　construction　efficiency　and　quality　of　railway　bridge　engineering.　A　kind　of　modular　prefabricated　solid　pier　used　in　railway　bridge　engineering　is　proposed，which　can　not　only　be　connected　by　longitudinal　segments，but　also　be　connected　horizontally　by　multiple　intercon⁃　nected　modules.　On　this　basis，based　on　ABAQUS　program，the　numerical　analysis　of　mechanical　properties　of　modular　prefabricated　bridge　piers　of　railway　bridges　under　monotonic　and　reciprocating　loads　is　carried　out，the　pier　performance　indexes　such　as　bearing　capacity，ductility　performance，hysteretic　performance　and　residual　dis⁃　placement　are　evaluated.　Modular　pier　have　reasonable　strength　and　relatively　stable　ductility　performance，espe⁃　cially　energy　dissipating　reinforcement　ratio，vertical　load，initial　prestress　level，and　pier　height　have　greater　im⁃　pact　on　the　performance　of　modular　prefabricated　bridge　piers.　At　the　same　time，modular　bridge　piers　helps　im⁃　prove　the　self-reset　capability　and　seismic　toughness　of　the　structure.　This　paper　aims　to　provide　technical　reference　for　the　popularization　and　application　of　modular　prefabricated　pier.　©　2022　Authors.　All　rights　reserved.
