摘要
城市建设用地的紧张加快了地下空间的开发,作为保障地下空间施工的深基坑支护也逐渐被重视。双排桩由于具有较大的侧向刚度、侧向变形小以及不需要内支撑的优点,被广泛应用于深基坑支护中。基于南京某个工程案例,介绍双排析的设计方案、计算分析以及施工要点,为今后该地区双排桩的应用提供参考与借鉴。
The tension in urban construction land has accelerated the development of underground space. Deep founda- tion pit support in protecting underground space construction has gradually been taken seriously. They were widely used in foundation pit support due to the advantages of double row pile having large lateral stiffness, small lateral deformation and with no need for support inside. Based on a case project in Nanjing, this paper introduces the design, calculation analysis and con- struction attention points of double row pile, which can provide reference for the application of double row pile in this area in the future.
