中文摘要：
寒区铁路运营隧道渗漏水因冬季结冰而造成重大安全隐患，影响行车安全。文中针对东北此类隧道渗漏水病害进行了试验整治，通过运用高精度探地雷达在隧道内进行渗漏水水源探测，针对不同渗漏水原因进行分类整治，采用堵排结合的施工技术和新型的马丽散防堵水材料进行堵水试验。实际工程验证了该技术和材料的安全可靠性。
英文摘要：
In the cold regions, the leakage of water in the operating existing railway tunnel will lead to the sigriificant security risk that affecting driving safety due to the winter freeze. This paper inakes a test remediation to seepage water of such tunnel. Through the Use of high-precision geology radar, we survey the water source of seepage water in the tunnel, classify and rectification the leakage of water by different reasons, and using the construction technology of combining the plugging and the drainage and the riew type of Malisan materials to test the plugging, validating the safety and reliability of the technology and materials by project.
