摘　　要：在基坑周边有建(构)筑物的情况下,往往对基坑支护的变形及止水性能有较高的要求,尤其在软土地层中[1],表现更加明显。采用放坡或单一的支护形式,很难取得理想效果。管桩水泥土复合桩支护同时具有挡土与抗渗的功能,是适用这种工况的一种新型支护结构,为对以后类似支护工程施工提供借鉴。In the case of the construction(structure) around the foundation pit, the deformation and water stopping performance of the foundation pit support are often required, especially in the soft soil layer. The performance is more obvious. It is difficult to achieve the ideal technological and economic effects by using slope or single support. Pipe pile cement soil composite pile support has the function of retaining soil and anti-seepage, and is a new type of support structure suitable for this type of operation.It provides references for similar support projects in the future.
