铁路新型中等高度桥墩的研究设计

铁路新型中等高度桥墩（简称铁路新型中墩）是一种适用于中等高度（10～40m）桥墩抢修的可拆装的制式器材，与已经停产的六五式铁路军用桥墩相比，具有部件种类少、重量轻、结构简单、拼组速度快等特点。重点介绍了铁路新型中墩的主要战术技术条件，其主要部件为立柱、撑杆、节点板、拼接板和紧固件等，结构型式主要由下垫梁、墩身和上垫梁组成。该器材可用于战时中等高度铁路桥墩的抢修和平时自然灾害桥梁的应急修复，或用作各种临时性施工辅助结构。

Research into the Design of New-type Medium-height Railway Bridge Piers

The new-type medium-height railway bridge pier （thereafter referred to as the new mediumheight pier） is a kind of standardized detachable equipment which is applicable to rush-repairing the medium-height piers（10 - 40 m） . Compared with type-65 military railway piers, whose production has been stopped, the new type medium-height pier has the advantages of being small in the number of components, light in weight, simple in structure, quick in assembling speed and so on. This paper focuses on the intro- duction to the tactical and technical conditions of the new medium-height pier, which is chiefly made up of posts, poles, gusset plates, splice plates, fasteners and so on, and whose structure is mainly composed of bottom-beams, piers and top-beams. The standardized detachable equipment can be used for rush-repairing the medium-height railway bridge piers at war-time or during natural disasters, or used as supplementary equipment for the construction of temporary structures.
