摘　　要：针对隧道在饱和动水砂层中自稳能力差、施工难度大的现状,通过现场注浆试验对水泥-水玻璃注浆压力、TSS管注浆工艺等进行了研究。研究表明新奥法中应用水泥-水玻璃双液注浆方法加固饱和动水砂层隧道可以取得较好的效果。Due to the present status of the poor stability and hard construction operation in dynamic water saturated sands of the tunnel, the site grouting test on the grouting pressure of the cement and water glass grouts and TSS tube grouting technology were researched. The research results showed that the application of the double grouting method with the cement and water glass to reinforce the tunnel construction in dynamic water saturated sands could have a good result.
