摘要
长江三角洲冲击平原淤泥质土分布广泛、厚度大,承压水水位高,工程地质条件复杂,深基坑工程维护施工困难。本工程采用了一种SMW工法+钻孔灌注桩结合预应力锚杆新的双排桩围护结构,工程实践表明,此种围护结构在该工程地质条件下支护效果良好,对大型软土深基坑围护结构施工具有借鉴意义。
Along the alluvial plain of the Yangtze River Delta, it is challenging to construct a deep foundation pit due to widely distributed and thick muddy soil, a high confined water level, and complex geological conditions. This project used a new retaining structure with double-row piles of the SMW construction method and bored piles combined with prestressed anchor. Engineering practices show that this retaining structure has a good supporting effect under the above geological conditions, and this paper provides a reference for the construction of retaining structures for large-scale, deep foundation pits.
