摘　　要：某广场超大基坑工程采用双排桩支护结构,发挥了该支护结构施工简便、刚度大、支护高度大的优点,避免设置内支撑,从而缩短了工期,降低了工程造价。对基坑支护结构位移变形的监测表明,该支护形式可显著减小围护结构的内力和变形,支护工程安全可靠,满足基坑稳定和变形控制的要求。A large practical excavation engineering is given here which the double- row piles is used as retaining structure. It took advantage of the merits of the double- row piles retaining structure, which makes construction simple, has greater stiffness and adapts to deep excavation. Thus it avoids setting up internal bracing and the construction period also becomes shorter. Project cost reduced too. The results show that this pattern can significantly reduce the bending moment and the deformation of retaining structure, which meet the requirements of the safety, reliability, stability and deformation requirements of support engineering.
