提高铁路隧道耐久性的系统探索

System Exploration of Improving the Durability of Railway Tunnel

铁路隧道病害已然成为威胁我国铁路安全运营的重大问题。本文从设计、施工、维护等方面系统地对铁路隧道耐久性的失效问题和提高措施进行分析思考,探索隧道耐久性的设计要点,提出了隧道施工的控制要领,用以延长隧道构造寿命,希望对隧道的施工设计以及维护提供有益的帮助。

Railway tunnel disease has become a major threat to the safety of railway operations in China. The paper made a systematic analysis and thinking on the failure problems of railway tunnel durability and its improving measures from design,construction and maintenance,explored the design points of tunnel durability,and put forward the control essentials of tunnel construction,so as to prolong the service life of tunnel structure. This paper was expected to provide a useful reference for tunnel design and maintenance.
