    • Abstract
  • The dewatering work of foundation pits is an important part of foundation pit engineering. Because this work may break the original balance of groundwater, and cause uneven settlement of the surrounding ground surface, and serious engineering accidents. At the same time, it wastes groundwater resources seriously. The anti-floatage anchor-jetting body (AAB) of deep foundation pits is a new important sealing structure of non-dewatering deep foundation pits. Based on the analysis of the mechanics of AAB in non-dewatering deep foundation pits, the effectiveness of the water-stop body and the safety of the support system, it is determined that the jetting body is in the elastic state. Using the theory of elasticity, the stress solutions of elastic thick plate under uniform and concentrated loads are established, the strength safety control method and the relevant method for calculating anti-uplift force of anti-floatage anchor are obtained, and the software for the design of sealing bottom water-stop body of AAB in non-dewatering deep foundation pits is developed. The monitoring data of foundation pit show that, in the excavation and service, the safety of the foundation pit meets the requirements of construction, although it has a small amount of side wall seepage and natural watering.
