Abstract Based on the application of horizontal jet grouting reinforcement technique in Shahalamao railway tunnel，the technologic parameter，construction process and improvement effect of this technique are mainly introduced. The work efficiency and material consume are analyzed also. It is shown that the horizontal jet grouting reinforcement technique can be used to construct the tunnel in soft sandy soil.

Key words： horizontal jet grouting reinforcement railway tunnel application techniqne
