| Abstract: | In the process of tunnel construction, pre-reinforcement technique by horizontal jet grouting pile is highly adaptable and operable, which improves the rock stability and foundation bearing capacity of highway tunnels in aeolian sand area. This paper discusses the reinforcement mechanism of rotary jet grouting under geological condition of aeolian sand stratum and constructing procedure of horizontal jet grouting reinforcement. Matters needing attention in construction are pointed out, providing reference for similar projects. |
