摘　　要：在极软岩地层中修建隧道,建造过程中各项风险均很高,若遇到高压富水区施工将寸步难行,严重的将会出现大型突涌及其引起的次生灾害。针对极软岩高压富水区隧道施工,从减压释能理论分析入手,形成了正洞注浆加固、两侧平导减压的减压释能工法。To build a tunnel in ultra soft rock strata will lead to various risks during the construction. Moreover there will be more difficulties if the tunnel is crossing the high-pressure and water-rich area,this could even lead to severe water inrush and secondary disasters caused by the inrush. Based on the pressure and energy relief theory,this paper puts forward the main tunnel grouting reinforcement and lateral horizontal decompression method to deal with the tunnel construction difficulty in high-pressure and water-rich area of ultra soft rock strata.
