对龙厦铁路象山隧道岩溶地段工程和水文地质情况做了简要说明，以YDK24+114～+144段的注浆循环为例，在注浆参数、材料选用、注浆顺序、施工工艺、机具设备配置以及注浆效果评定等方面，对岩溶地段全断面超前注浆加固技术做了介绍，为今后类似工程积累了经验。

The engineering geology and hydrogeology of the karst section of Xiangshan tunnel on LongyanXiamen railway is presented. The fullface advance grouting technology for karst area, including grouting parameters, grouting materials, grouting procedure, grouting technique, grouting equipment and grouting effect assessment, are described, with the grouting in YDK24+114～+144 section of Xiangshan tunnel as an example. This paper can provide reference for similar projects in the future.
