公跨铁立交桥上跨既有铁路线桥梁安装，施工难度大，安全性要求高，时效性要求强，而公路与铁路斜交时难度更大。以某公铁立交桥为背景，系统介绍施工方案比选，无防护棚架防护跨线制梁与安装方案的具体工艺技术和安全措施，方案安全而高效，可为同类工程提供经验参考。
公跨鐵立交橋上跨既有鐵路線橋樑安裝，施工難度大，安全性要求高，時效性要求彊，而公路與鐵路斜交時難度更大。以某公鐵立交橋為揹景，繫統介紹施工方案比選，無防護棚架防護跨線製樑與安裝方案的具體工藝技術和安全措施，方案安全而高效，可為同類工程提供經驗參攷。

It is difficult to install highway-railway overpass on existing railway lines due to the high requirement in construction, security and timeliness, especially for X-type highway arch bridges. This paper, taking highway-railway overpass as the research object, systematically introduces the comparison and selection of construction schemes and the specific technology and safety measures of installation scheme of beaming across lines without protective scaffolding. It then finds out the secure and efficient scheme , which can provide a reference for the simi?lar engineering.
