高速铁路隧道关键科学问题及发展趋势

Key Scientific Problems and Development Tendency of High Speed Railway Tunnel

分析了高速铁路隧道的主要特点,即隧道断面大,长大隧道多,地质条件复杂,使得施工风险极高,可靠性要求高,耐久性控制严格。高速铁路隧道通常成为高速铁路建设的控制性工程,因而为了安全快速地建成高速铁路网,必须在复杂长大隧道修建技术方面实现新的突破。为此提出了高速铁路隧道的关键科学问题,在对现有研究工作进行总结的基础上,提出了高速铁路隧道应重点研究的内容与发展方向。建议通过系统研究建立高速铁路隧道工程的设计理论与技术体系,形成中国隧道建造方法。

The main characteristics of high speed railway tunnels were analyzed,including large tunnel sections,a lot of long tunnels,poor geology and complex topography,which leading to extremely high construction risk,high reliability requirement and strict durability control.Thus the high speed railway tunnels usually become control projects for high speed railway construction.Therefore,in order to build the high speed railway network safely and quickly,the new breakthroughs must be made in the construction technology of complex long tunnels with large section.The key scientif ic problems of high speed railway tunnels were proposed.On the basis of summarizing the existing research work,the content and development directions of the key research on high speed railway tunnels were put forward.It is suggested that the design theory and technical system of high speed railway tunnel engineering should be established systematically to form the method of tunnel construction in China.
