摘　　要：介绍了一种超大断面箱涵顶进注浆施工工艺,通过向钢管幕和箱涵中间的建筑间隙内注入厚浆及稀浆两种不同的浆液,在减少箱涵顶进周边摩阻力同时,还能够有效的控制地面沉降,确保箱涵的顺利施工。This paper introduces a technology of synchronous and supplementary grouting in box-culvert propulsion.By injecting thick slurry and thin slurry into the building space between steel pipe-roofing and box-culvert synchronously,the friction resistance of box culvert advancing is reduced,the ground settlement is reduced,and the smooth jacking of box culvert is ensured.

关 键 词：箱涵 管幕 注浆 摩阻力
