摘　　要：简要介绍双排桩支护结构体系,运用MIDAS-GTS有限元软件建立考虑桩土接触的三维有限元模型,对比分析了排距、刚度、桩长等参数对支护结构变形受力的影响,得出一些对工程应用有价值的结论。This article simply introduces the retaining structure of double-row piles.By using MIDAS-GTS finite element software,considering the pile-soil contact,through the establishment of three-dimensional finite element model,analyzes the impact on the deformation and force when excavate deep foundation by modifying the original model as the piles row spacing、pile stiffness and embedded depth.Through comparative analysis of the result,then summarize the general work rules of double-row piles through comparative analysis of the results,finally,draw some valuable conclusions for engineering applications.
