| 中文摘要:通过工程实例，介绍了在无传统换撑(即地下一层楼板)条件下的一种换撑方案，即采用一排钻孔灌注桩作为挡土结构，坑内设置2道钢筋混凝土内支撑，钻孔灌注桩外侧设置2排深层水泥搅拌桩作止水帷幕，同时可防止淤泥挤入。实际开挖证明该换撑做法是安全、可靠的。 |

| Abstract:With an engineering case, the paper introduced a new support replacement plan when there is no condition for traditional support replacement construction. A row of bored cast-in-place piles are taken as retaining structure, 2 lines of steel concrete inner support in the excavation, 2 rows of deep cement mixing pile outside the piles as water-stop curtain which can prevent silt to get in. It is proved that this support replacement is safe and reliable. |
