摘要/Abstract

摘要： 姜路岭隧道地处青藏高原多年冻土地区，其高海拔、高寒、缺氧环境下多年冻土及软弱大变形围岩的公路隧道设计施工技术属国内乃至亚洲首例，也是共（和）玉（树）高速公路重难点控制性工程。为研究姜路岭隧道施工过程中的水热力（变形）状态及其演变，采用冻土工程水热力耦合计算理论及数值仿真程序，模拟了该隧道三个关键施工步骤的水热力分布规律，以此提出了隧道修建过程中的重点监测位置及注意事项。研究成果可为姜路岭多年冻土隧道的设计施工提供理论指导和技术支持，进而为类似寒区隧道工程的设计和施工提供参考依据。

Abstract: Jiangluling Tunnel is located in permafrost region in the Tibetan Plateau, and it is difficult to be designed and constructed because of permafrost and weak deformed surrounding rock in high altitude, cold climate and poor oxygen environment, which is the first case in Asia, even in the world. Meanwhile, it is an important governing engineering of the Gonghe-Yushu Expressway. In order to explore moisture-heat-mechanics state and variation of surrounding rock during the Jiangluling Tunnel construction, a moisture-heat-mechanics coupled model on frozen soil engineering and corresponding numerical software is used to simulate the moisture, temperature and deformation variations of the surrounding rock in three key construction steps, according to which an important monitoring position and some attentions were pointed out during the tunnel construction. The results are expected to be theoretical guidance and technical support for the design and construction of the Jiangluling Tunnel in permafrost region, and further it is useful for designing and constructing a similar tunnel in cold regions.

Key words: permafrost, tunnel, numerical simulation, temperature, deformation
