| 摘 要： | 对既有铁路隧道尤其是重载铁路隧道运营过程中出现的基底病害进行了研究,重点论述和分析病害检测、评估与整治措施等方面的内容。针对铁路隧道中以地下水为诱因的基底病害,介绍了"井点降水+注浆"这种适合既有铁路隧道基底水害"疏堵结合"的复合式整治措施,并在大秦铁路九山隧道基底病害整治工程中加以推广应用,取得了良好的工程效果,可为类似工程提供参考。

| Abstract: | The base disease in the operation process of existing railway tunnel, especially for heavy haul railway tunnel was studied. The main point focused on the discussion and analysed of base disease detection, assessment and remediation measures etc. Based on the existing base disease of railway tunnel caused by the groundwater, a new composite remediation measure called ＂well point dewatering ＋ grouting＂ has been introduced, which can be used in the repairing of existing rail-way tunnel basement water damage. This composite remediation measure has been widely popularized and applied in the project of Datong-Qinhuangdao Railway Jiushan Tunnel base disease control. This project achieved good engineering results, which can provide reference for similar projects. |
