秦岭Ⅰ线隧道的建成和Ⅱ线隧道平行导坑的贯通,开创了我国铁路建设史上多项全国纪录: 秦岭Ⅰ线隧道长18.452km,是我国和亚州最长的标准轨距铁路单线隧道。 秦岭隧道在初测前增加了一个加强地质勘测的子阶段,这是国内首次试点。采用大面积地质调绘的综合勘探方法,取得了高质量的地质勘测成果,其地质预报的准确性堪称国内第一。
The completion of Qinling Ⅰ tunnel and parallel tunneling of Ⅱ tunnel opened many national records in the history of railway construction in our country. The Qinling Ⅰ tunnel is 18.452km in length, which is the longest standard gauge railway tunnel in China and Asia. Qinling tunnel in the initial test before adding a sub-stage to enhance geological survey, which is the first pilot. Using large-scale geological reconnaissance integrated exploration methods, and achieved high-quality geological survey results, the accuracy of its geological forecast called the first in China.
