摘　　要：以莆田某超大软土深基坑为例,介绍了在软土地区采用双排桩结合锚杆的设计实例。采用有限元软件PLAXIS对支护结构进行了数值分析,研究了双排桩—锚杆复合结构的受力变形规律,通过与监测数据进行对比,表明双排桩增设锚杆以后,可以有效地控制变形和改善支护桩受力,对类似工程具有指导意义。Based on a super and deep foundation pit in soft soils in Putian, This paper introduces the use of double - row pile plus anchor construction in soft soils area. The finite element software PLAXIS is used to simulate and analysis the retaining structure, and the stress and deformation rules of double - row piles plus anchor construction is studied. By comparing with the monitoring data, the double - row piles plus anchor construction can effectively control the deforma- tion and improve the stress of piles is proved. It has guidance significance for similar projects.
