【 摘 要 】

Start your Through the practice of curtain grouting in the fault zone F2 of Zhongjiashan Tunnel in Jiangxi Province, we explored effective methods for the treatment of fault crushing zone, including key parameters such as grouting drilling design and grouting material selection. The research results show that the full-section grouting method is to treat The effective means of water and mud outburst disasters in the fault crushing zone can be used as a reference for a full-section grouting method. The cement grout and the cement-water glass slurry can be used together to provide an effective grouting material for the curtain grouting treatment in the fault crushing zone; In the implementation of full-section curtain grouting, an outside-in grouting method should be adopted.
