摘　　要：应用PLAXIS建立了深基坑地连墙支护模拟模型,该模型可对地连墙支护结构,进行开挖支护施工过程的动态模拟分析。通过现场对基坑水平位移、竖向位移、锚杆内力等进行监测并得到相应数据。将模拟模型与现场观测数据进行对比分析,说明建立的数值模拟分析模型,能够反映地连墙支护的基坑,在开挖过程中的受力和变形特征。这也为深基坑地连墙支护技术的设计和施工提供指导,并对深入了解地连墙支护作用的机理有较大意义。PLAXIS is used to establish simulation model of underground continuous wall in deep foundation pit support, which provides dynamic simulation analysis for construction process of underground continuous wall support excavation. Data of foundation pit horizontal displacement, vertical displacement and inner force of bolt are received by field monitoring. By comparison analysis of simulation model and field data, it is proved that the numerical simulation analysis model can reflect force and deformation characteristics in underground continuous wall support excavation. Besides, it provides guidance for underground continuous wall support design and construction, and is of great significance in further understanding of underground continuous wall support mechanism.
