在隧道工程中,渗漏水会造成钢轨锈蚀、轨枕腐蚀、道床翻浆冒泥、混凝土腐蚀等危害,而隧道工程中的许多渗漏水发生在施工缝及变形缝处。文章通过对冻土地区隧道水损害特征及机理的调研和分析,在实践验证的基础上,总结出了冻土地区隧道防水系统的应用材料及施工工艺。
In tunnel engineering, seepage water can cause rail corrosion, sleeper corrosion, ballasting mud on the roadbed, corrosion of concrete and other hazards. Many seepage water in tunnel construction occurs at construction joints and deformation joints. Based on the investigation and analysis of the characteristics and mechanism of tunnel water damage in permafrost region, the article summarizes the application materials and construction technology of tunnel waterproofing system in permafrost region.
