在铁路既有线改造工程并行段桥涵施工过程中,为保证既有线在不中断行车情况下的营运安全,既有线防护是关键。该文以改建铁路沪汉蓉通道襄樊至胡家营段增建第二线站前工程XYS-02标段并行段箱型桥接长（桩号里程为K25＋134（2~10.0 m））施工为例,较为详细地介绍了铁路既有线改造工程并行段桥涵施工中采用挖孔桩防护的设计原理。文中提供的铁路既有线改造工程并行段桥涵施工中采用挖孔桩防护方案设计可作为同类工程施工的参考依据。
In the transformation of existing railway bridge and culvert construction in parallel paragraph, in order not to interrupting the operation of existing track, protection is the key. In this article, it used the channel of shanghai to Wuhan and Chengdu Railway , From Xiangfan to Hujiaying additional second-line business segment station project tenders XYS-02 parallel bridging long box above （mileage for K25 ＋ 134 （2--10.0 m）） as a example. Give a more detailed description of the design principle that used protection with dug pile in transformation of existing railway bridge and culvert construction in par- allel paragraph. Text provided protetcing with dug pile in transformation of existing railway bridge and culvert construction in parallel paragraph can be used as reference of similar works.
