摘要
近年来我国社会经济的快速发展,交通路网越来越发达,新建公路工程跨越原有线路的情况时有出现。受施工环境的限制,采用门式墩跨越既有线路的设计越来越多。以实际工程为例,首先对跨既有铁路桥梁门式墩盖梁的施工方案进行了分析,然后对跨既有铁路桥梁门式墩盖梁的施工技术进行了探讨。
In recent years, the social economy of China is quickly developed. The traffic road network is becoming more and more developed. There are often the newly built highway projects spanning the existing lines. Limited by the construction environment, the design of gate-type pier spanning the existing line is becoming more and more. Taking a practical project as an example, the article firstly analyzes the construction scheme of the gate-type pier bent cap of bridge spanning the existing railway, and then discusses the construction technology of the gate-type pier bent cap of bridge spanning the existing railway.
