摘要
现有的深基坑围护结构种类及技术已经很成熟,相关技术要有相关的适宜的条件才能使生产获得更大的效益。本文以南京地铁明发广场站的实际情况,结合咬合桩工艺与设备,综合阐述了咬合桩施工工艺目前不适用于软土层与深基坑嵌岩桩的施工。
The existing methods and technology of deep foundation pit retaining structure is already very mature. However, the application of related technology needs the related suitable conditions, which can generate greater benefits. Based on the practice of Mingfa square station of Nanjing metro, this paper presents the technology and equipment of secant pile construction, and expounds the secant pile construction technology is not suitable for the construction in soft soil and deep foundation pit of rock-socketed pile.
