在我国经济飞速发展的过程中,铁路网的建设具有极大的重要性,它推动着整个经济体的向前发展。近年来国家对于铁路的建设也愈加重视,越来越多的铁路建设工程投入建设。但在规划中常会受到地貌条件等制约,使得铁路建设中新建的隧道与既有隧道之间的设计距离相近,造成对既有隧道结构损坏,同时也会对新建隧道的施工带来安全隐患。所以我们需要分析邻近隧道施工对既有隧道的影响,做到科学合理施工。
In the process of rapid economic development in our country, the construction of the railway network is of great importance and it has promoted the development of the entire economy. In recent years, the state has also paid more attention to the construction of the railway and more and more railway construction projects have been put into construction. However, the planning is often constrained by the landform and other constraints, which makes the design distance between the newly built tunnels in the railway construction and the existing tunnels similar, resulting in damage to the existing tunnel structures as well as potential safety problems for the construction of new tunnels. Therefore, we need to analyze the influence of adjacent tunnel construction on the existing tunnel so as to achieve scientific and reasonable construction.
