摘　　要：针对哈大高铁某隧道伸缩缝及底座板施工缝渗水情况,进行了室内浆材试验和现场灌浆试验研究,结果表明水溶性聚氨酯浆材适合于高寒地区伸缩缝的渗漏水处理,而改性环氧浆材适用于轨道板座板施工缝的渗水处理。经过3年多的运行检验,试验处理的伸缩缝和施工缝均未出现新的渗漏水,达到了预期治理效果,可在高寒地区其他隧道渗漏水治理中推广使用。The article mainly studied the grouting technology by indoor experiments and field tests for expansion joint and construction joint leakage treatment for Hada high-speed railway tunnel. The test showed that the water soluble polyurethane was suitable for expansion joint treatment in frigid zone, and the modified epoxy resin grouting material was suitable for construction joint treatment in slab track. After more than three years of operation and inspection, no seepage was found in the treated tunnel and achieved the expected treatment target, which can give a reference for the similar projects in frigid zone.
