摘要
铁路桥梁梁体施工中箱梁支座板空鼓问题是一个普遍存在的质量隐患。本文结合成贵铁路黔西制梁场646孔预制箱梁的施工经验,重点剖析了高速铁路箱梁支座板空鼓产生的原因及防治措施,希望能给铁路箱梁安全质量施工带来一些参考。
Hollowing of bearing plate for box beam in high-speed railway is a common quality hidden trouble. In view of the construction of 646 holes precast concrete box girders of Qianxi beam fabricating yard in Chengdu-Guiyang High-speed Rail- way, cause and preventive measures for hollowing of bearing plate of box beam in high-speed railway was deeply analyzed in this paper, hoping to provide some references for the safety and quality of railway box beam construction.
