土钉与钢管桩在深基坑处理流砂中的应用

结合某商业住宅楼基坑支护工程实例，将抗滑桩技术、土钉与钢管桩联合支护技术相结合应用于基坑发生局部流砂部位的处理。在基坑发生流砂且周边建筑物距基坑比较近的情况下，该方法具有支护和处理流砂的双重作用，是一种很实用的方法，可有效缩短工期，成本低、施工安全。

The Combination of Soil Nail and Steel Pipe Pile Applications in Deep Excavations within Quicksand Layers

The application of the landslide treatment piles in the deep excavation within the localized quicksand locations for a commercial residential building is presented in this paper. The supporting system for this deep excavation system consists of using both soil nailing and steel pipe piles. In areas that the quicksand was presented during the deep excavation in the urban areas, where the adjacent building structures are closed by, this practical method can serve the purposes of both supporting and treating the quicksand. It also has low cost, fast and safe construction characteristics.
