基于中印规范的大件运输安全过桥实例分析

Example Analysis of Large-cargo Transportation Safety across River Based on Specifications of China and India

大件设备通过桥梁时需进行承载能力的准确评估,这是确保桥梁和运输设备安全的重要手段。基于中印两国桥梁设计规范,采用荷载组合对比法对孟加拉国北部公路桥梁205 t大件设备运输项目中缺少设计图纸的PC简支梁桥进行了承载能力分析与计算,判定了沿线桥梁能否满足大件运输安全通行,并得出了一些结论,以期为同类工程提供借鉴。

The bearing capacity of bridge should be accurately evaluated when the large equipment passes over the bridge. This is the important means to ensure the bridge safety and the equipment transportation safety. Based on the bridge design specifications of China and India, the load combination correlation method is used to analyze and calculate the bearing capacity of a PC simple-supported beam bridge without the design drawings in the 205 t large equipment transportation project on the northern highway bridges in Bangladesh, judge whether or not the bridges along the line meet the safe traffic of large-cargo transportation, and achieve some conclusions in order to provide the reference for the similar projects.
