摘要
从相关设计规范修订及最新版的《铁路桥涵设计基本规范》对铁路活载的有关规定着手,提出八三墩能否在现行铁路中-活载条件下正常使用的问题,结合铁路活载提高所引起的八三墩梁跨结构相关参数改变情况,说明为确保安全应对相关参数进行检算,并提供了算例。
In the light of the revision of the design criteria and regulations about railway live loads in the Fundamental Code for the Design of Railway Bridges and Culverts, the paper raises a question whether type-83 piers can be normally used for live loads of the current P. R.C. railway standard. Taking account of the influenees of the ehange in the related parameters of the beam eaused by the inerease of railway live loads, it deals with the neeessity of eheeking all the related teehnieal parameters to ensure safety, with practical calculation examples presented.
