基于六五式铁路军用桥墩的重载铁路墩部抢修应用研究

A Study of the 65-Type Railway Military Pier-Based Rush Repair of Bridge Piers for Heavy-Loaded Railways

为解决重载铁路在遭受平时自然灾害或突发事件破坏时的桥梁应急抢修问题,选取六五墩为研究对象,根据拟定的计算工况,利用ZH荷载对六五墩重新进行受力分析,探求六五墩用于重载铁路墩部抢修的可行性。结果表明:六五墩用于重载铁路墩部抢修时,不能依据六五墩手册中现有墩型直接使用。依据配合梁跨度和ZH荷载系数,六五墩通过局部加固后可选择适当的墩型进行重载铁路墩部抢修。

In order to solve the problem of rush-repairing heavy-loaded railways when they are damaged by natural disasters or sudden events in peacetime,65-type railway military piers are chosen as the object of our research.According to the proposed calculation conditions,a stress analysis of the 65-type railway military pier is carried out again by using the ZH load to explore the application feasibility of the 65-type railway military piers to rush repairing the bridge piers of heavy-loaded railways.The results show that the existing pier type of the 65-type piers prescribed in the manual of the 65-type piers can not be directly used for rush repairing the bridge piers of heavy-loaded railways.According to the different spans of matching beams and ZH load coefficients,some proper pier types of the 65-type railway military piers can be used for rush repairing the bridge piers of heavy-loaded railways after they are locally reinforced.
